/*************************************************************************
Sparse matrix structure.
You should use ALGLIB functions to work with sparse matrix. Never try to
access its fields directly!
NOTES ON THE SPARSE STORAGE FORMATS
Sparse matrices can be stored using several formats:
* Hash-Table representation
* Compressed Row Storage (CRS)
* Skyline matrix storage (SKS)
Each of the formats has benefits and drawbacks:
* Hash-table is good for dynamic operations (insertion of new elements),
but does not support linear algebra operations
* CRS is good for operations like matrix-vector or matrix-matrix products,
but its initialization is less convenient - you have to tell row sizes
at the initialization, and you have to fill matrix only row by row,
from left to right.
* SKS is a special format which is used to store triangular factors from
Cholesky factorization. It does not support dynamic modification, and
support for linear algebra operations is very limited.
Tables below outline information about these two formats:

/*************************************************************************
This function creates sparse matrix in a Hash-Table format.
This function creates Hast-Table matrix, which can be converted to CRS
format after its initialization is over. Typical usage scenario for a
sparse matrix is:
1. creation in a Hash-Table format
2. insertion of the matrix elements
3. conversion to the CRS representation
4. matrix is passed to some linear algebra algorithm
Some information about different matrix formats can be found below, in
the "NOTES" section.
INPUT PARAMETERS
M - number of rows in a matrix, M>=1
N - number of columns in a matrix, N>=1
K - K>=0, expected number of non-zero elements in a matrix.
K can be inexact approximation, can be less than actual
number of elements (table will grow when needed) or
even zero).
It is important to understand that although hash-table
may grow automatically, it is better to provide good
estimate of data size.
OUTPUT PARAMETERS
S - sparse M*N matrix in Hash-Table representation.
All elements of the matrix are zero.
NOTE 1
Hash-tables use memory inefficiently, and they have to keep some amount
of the "spare memory" in order to have good performance. Hash table for
matrix with K non-zero elements will need C*K*(8+2*sizeof(int)) bytes,
where C is a small constant, about 1.5-2 in magnitude.
CRS storage, from the other side, is more memory-efficient, and needs
just K*(8+sizeof(int))+M*sizeof(int) bytes, where M is a number of rows
in a matrix.
When you convert from the Hash-Table to CRS representation, all unneeded
memory will be freed.
NOTE 2
Comments of SparseMatrix structure outline information about different
sparse storage formats. We recommend you to read them before starting to
use ALGLIB sparse matrices.
NOTE 3
This function completely overwrites S with new sparse matrix. Previously
allocated storage is NOT reused. If you want to reuse already allocated
memory, call SparseCreateBuf function.

Fmt - desired storage format of the output, as returned by
SparseGetMatrixType() function:
* 0 for hash-based storage
* 1 for CRS
* 2 for SKS
OUTPUT PARAMETERS
S0 - sparse matrix in requested format.
NOTE: in-place conversion wastes a lot of memory which is used to store
temporaries. If you perform a lot of repeated conversions, we
recommend to use out-of-place buffered conversion functions, like
SparseCopyToBuf(), which can reuse already allocated memory.

Update of Cholesky decomposition: "fixing" some variables.
This function uses internally allocated buffer which is not saved between
subsequent calls. So, if you perform a lot of subsequent updates,
we recommend you to use "buffered" version of this function:
SPDMatrixCholeskyUpdateFixBuf().
"FIXING" EXPLAINED:
Suppose we have N*N positive definite matrix A. "Fixing" some variable
means filling corresponding row/column of A by zeros, and setting
diagonal element to 1.
For example, if we fix 2nd variable in 4*4 matrix A, it becomes Af:
( A00 A01 A02 A03 ) ( Af00 0 Af02 Af03 )
( A10 A11 A12 A13 ) ( 0 1 0 0 )
( A20 A21 A22 A23 ) => ( Af20 0 Af22 Af23 )
( A30 A31 A32 A33 ) ( Af30 0 Af32 Af33 )
If we have Cholesky decomposition of A, it must be recalculated after
variables were fixed. However, it is possible to use efficient
algorithm, which needs O(K*N^2) time to "fix" K variables, given
Cholesky decomposition of original, "unfixed" A.
INPUT PARAMETERS:
A - upper or lower Cholesky factor.
array with elements [0..N-1, 0..N-1].
Exception is thrown if array size is too small.
N - size of matrix A, N>0
IsUpper - if IsUpper=True, then A contains upper Cholesky factor;
otherwise A contains a lower one.
Fix - array[N], I-th element is True if I-th variable must be
fixed. Exception is thrown if array size is too small.
BufR - possibly preallocated buffer; automatically resized if
needed. It is recommended to reuse this buffer if you
perform a lot of subsequent decompositions.
OUTPUT PARAMETERS:
A - updated factorization. If IsUpper=True, then the upper
triangle contains matrix U, and the elements below the main
diagonal are not modified. Similarly, if IsUpper = False.
NOTE: this function always succeeds, so it does not return completion code
NOTE: this function checks sizes of input arrays, but it does NOT checks
for presence of infinities or NAN's.
NOTE: this function is efficient only for moderate amount of updated
variables - say, 0.1*N or 0.3*N. For larger amount of variables it
will still work, but you may get better performance with
straightforward Cholesky.

/*************************************************************************
Sparse LU decomposition with column pivoting for sparsity and row pivoting
for stability. Input must be square sparse matrix stored in CRS format.
The algorithm computes LU decomposition of a general square matrix
(rectangular ones are not supported). The result of an algorithm is a
representation of A as A = P*L*U*Q, where:
* L is lower unitriangular matrix
* U is upper triangular matrix
* P = P0*P1*...*PK, K=N-1, Pi - permutation matrix for I and P[I]
* Q = QK*...*Q1*Q0, K=N-1, Qi - permutation matrix for I and Q[I]
This function pivots columns for higher sparsity, and then pivots rows for
stability (larger element at the diagonal).
INPUT PARAMETERS:
A - sparse NxN matrix in CRS format. An exception is generated
if matrix is non-CRS or non-square.
PivotType- pivoting strategy:
* 0 for best pivoting available (2 in current version)
* 1 for row-only pivoting (NOT RECOMMENDED)
* 2 for complete pivoting which produces most sparse outputs
OUTPUT PARAMETERS:
A - the result of factorization, matrices L and U stored in
compact form using CRS sparse storage format:
* lower unitriangular L is stored strictly under main diagonal
* upper triangilar U is stored ON and ABOVE main diagonal
P - row permutation matrix in compact form, array[N]
Q - col permutation matrix in compact form, array[N]
This function always succeeds, i.e. it ALWAYS returns valid factorization,
but for your convenience it also returns boolean value which helps to
detect symbolically degenerate matrices:
* function returns TRUE, if the matrix was factorized AND symbolically
non-degenerate
* function returns FALSE, if the matrix was factorized but U has strictly
zero elements at the diagonal (the factorization is returned anyway).

The algorithm computes Cholesky decomposition of a symmetric positive-

This function is a more efficient alternative to general, but slower
SparseCholeskyX(), because it does not create temporary copies of the
target. It performs factorization in-place, which gives best performance
on low-profile matrices. Its drawback, however, is that it can not perform
profile-reducing permutation of input matrix.
INPUT PARAMETERS:
A - sparse matrix in skyline storage (SKS) format.
N - size of matrix A (can be smaller than actual size of A)
IsUpper - if IsUpper=True, then factorization is performed on upper
triangle. Another triangle is ignored (it may contant some
data, but it is not changed).
OUTPUT PARAMETERS:
A - the result of factorization, stored in SKS. If IsUpper=True,
then the upper triangle contains matrix U, such that
A = U^T*U. Lower triangle is not changed.
Similarly, if IsUpper = False. In this case L is returned,
and we have A = L*(L^T).
Note that THIS function does not perform permutation of
rows to reduce bandwidth.
RESULT:
If the matrix is positive-definite, the function returns True.
Otherwise, the function returns False. Contents of A is not determined
in such case.
NOTE: for performance reasons this function does NOT check that input
matrix includes only finite values. It is your responsibility to
make sure that there are no infinite or NAN values in the matrix.

Input parameters:
A - source matrix. array[0..M-1, 0..N-1]
M - number of rows in matrix A.
N - number of columns in matrix A.
Output parameters:
A - matrices Q, B, P in compact form (see below).
TauQ - scalar factors which are used to form matrix Q.
TauP - scalar factors which are used to form matrix P.
The main diagonal and one of the secondary diagonals of matrix A are
replaced with bidiagonal matrix B. Other elements contain elementary
reflections which form MxM matrix Q and NxN matrix P, respectively.
If M>=N, B is the upper bidiagonal MxN matrix and is stored in the
corresponding elements of matrix A. Matrix Q is represented as a
product of elementary reflections Q = H(0)*H(1)*...*H(n-1), where
H(i) = 1-tau*v*v'. Here tau is a scalar which is stored in TauQ[i], and
vector v has the following structure: v(0:i-1)=0, v(i)=1, v(i+1:m-1) is
stored in elements A(i+1:m-1,i). Matrix P is as follows: P =
G(0)*G(1)*...*G(n-2), where G(i) = 1 - tau*u*u'. Tau is stored in TauP[i],
u(0:i)=0, u(i+1)=1, u(i+2:n-1) is stored in elements A(i,i+2:n-1).
If M<N, B is the lower bidiagonal MxN matrix and is stored in the
corresponding elements of matrix A. Q = H(0)*H(1)*...*H(m-2), where
H(i) = 1 - tau*v*v', tau is stored in TauQ, v(0:i)=0, v(i+1)=1, v(i+2:m-1)
is stored in elements A(i+2:m-1,i). P = G(0)*G(1)*...*G(m-1),
G(i) = 1-tau*u*u', tau is stored in TauP, u(0:i-1)=0, u(i)=1, u(i+1:n-1)
is stored in A(i,i+1:n-1).
EXAMPLE:
m=6, n=5 (m > n): m=5, n=6 (m < n):
( d e u1 u1 u1 ) ( d u1 u1 u1 u1 u1 )
( v1 d e u2 u2 ) ( e d u2 u2 u2 u2 )

( v1 v2 v3 d e ) ( v1 v2 e d u4 u4 )
( v1 v2 v3 v4 d ) ( v1 v2 v3 e d u5 )
( v1 v2 v3 v4 v5 )
Here vi and ui are vectors which form H(i) and G(i), and d and e -
are the diagonal and off-diagonal elements of matrix B.

matrix B (upper or lower) representing it as B = Q*S*P^T, where Q and P -
orthogonal matrices, S - diagonal matrix with non-negative elements on the
main diagonal, in descending order.
The algorithm finds singular values. In addition, the algorithm can
calculate matrices Q and P (more precisely, not the matrices, but their
product with given matrices U and VT - U*Q and (P^T)*VT)). Of course,
matrices U and VT can be of any type, including identity. Furthermore, the
algorithm can calculate Q'*C (this product is calculated more effectively
than U*Q, because this calculation operates with rows instead of matrix
columns).
The feature of the algorithm is its ability to find all singular values
including those which are arbitrarily close to 0 with relative accuracy
close to machine precision. If the parameter IsFractionalAccuracyRequired
is set to True, all singular values will have high relative accuracy close
to machine precision. If the parameter is set to False, only the biggest
singular value will have relative accuracy close to machine precision.
The absolute error of other singular values is equal to the absolute error
of the biggest singular value.
Input parameters:
D - main diagonal of matrix B.
Array whose index ranges within [0..N-1].
E - superdiagonal (or subdiagonal) of matrix B.
Array whose index ranges within [0..N-2].
N - size of matrix B.
IsUpper - True, if the matrix is upper bidiagonal.
IsFractionalAccuracyRequired -
THIS PARAMETER IS IGNORED SINCE ALGLIB 3.5.0
SINGULAR VALUES ARE ALWAYS SEARCHED WITH HIGH ACCURACY.
U - matrix to be multiplied by Q.
Array whose indexes range within [0..NRU-1, 0..N-1].
The matrix can be bigger, in that case only the submatrix
[0..NRU-1, 0..N-1] will be multiplied by Q.
NRU - number of rows in matrix U.
C - matrix to be multiplied by Q'.
Array whose indexes range within [0..N-1, 0..NCC-1].
The matrix can be bigger, in that case only the submatrix
[0..N-1, 0..NCC-1] will be multiplied by Q'.
NCC - number of columns in matrix C.
VT - matrix to be multiplied by P^T.
Array whose indexes range within [0..N-1, 0..NCVT-1].
The matrix can be bigger, in that case only the submatrix
[0..N-1, 0..NCVT-1] will be multiplied by P^T.
NCVT - number of columns in matrix VT.
Output parameters:
D - singular values of matrix B in descending order.
U - if NRU>0, contains matrix U*Q.
VT - if NCVT>0, contains matrix (P^T)*VT.
C - if NCC>0, contains matrix Q'*C.
Result:
True, if the algorithm has converged.
False, if the algorithm hasn't converged (rare case).
NOTE: multiplication U*Q is performed by means of transposition to internal
buffer, multiplication and backward transposition. It helps to avoid
costly columnwise operations and speed-up algorithm.
Additional information:
The type of convergence is controlled by the internal parameter TOL.
If the parameter is greater than 0, the singular values will have
relative accuracy TOL. If TOL<0, the singular values will have
absolute accuracy ABS(TOL)*norm(B).
By default, |TOL| falls within the range of 10*Epsilon and 100*Epsilon,
where Epsilon is the machine precision. It is not recommended to use
TOL less than 10*Epsilon since this will considerably slow down the
algorithm and may not lead to error decreasing.

The algorithm calculates the singular value decomposition of a matrix of
size MxN: A = U * S * V^T
The algorithm finds the singular values and, optionally, matrices U and V^T.
The algorithm can find both first min(M,N) columns of matrix U and rows of
matrix V^T (singular vectors), and matrices U and V^T wholly (of sizes MxM
and NxN respectively).
Take into account that the subroutine does not return matrix V but V^T.
Input parameters:
A - matrix to be decomposed.
Array whose indexes range within [0..M-1, 0..N-1].
M - number of rows in matrix A.
N - number of columns in matrix A.
UNeeded - 0, 1 or 2. See the description of the parameter U.
VTNeeded - 0, 1 or 2. See the description of the parameter VT.
AdditionalMemory -
If the parameter:
* equals 0, the algorithm doesn't use additional
memory (lower requirements, lower performance).
* equals 1, the algorithm uses additional
memory of size min(M,N)*min(M,N) of real numbers.
It often speeds up the algorithm.
* equals 2, the algorithm uses additional
memory of size M*min(M,N) of real numbers.
It allows to get a maximum performance.
The recommended value of the parameter is 2.
Output parameters:
W - contains singular values in descending order.
U - if UNeeded=0, U isn't changed, the left singular vectors
are not calculated.
if Uneeded=1, U contains left singular vectors (first
min(M,N) columns of matrix U). Array whose indexes range
within [0..M-1, 0..Min(M,N)-1].
if UNeeded=2, U contains matrix U wholly. Array whose
indexes range within [0..M-1, 0..M-1].
VT - if VTNeeded=0, VT isn't changed, the right singular vectors
are not calculated.
if VTNeeded=1, VT contains right singular vectors (first
min(M,N) rows of matrix V^T). Array whose indexes range
within [0..min(M,N)-1, 0..N-1].
if VTNeeded=2, VT contains matrix V^T wholly. Array whose
indexes range within [0..N-1, 0..N-1].

This function initializes subspace iteration solver. This solver is used

required. When K approaches N, this solver is slower than complete dense
EVD
* when problem matrix is sparse (and/or is not known explicitly, i.e. only
matrix-matrix product can be performed)

This function sets stopping critera for the solver:
* error in eigenvector/value allowed by solver
* maximum number of iterations to perform
INPUT PARAMETERS:
State - solver structure
Eps - eps>=0, with non-zero value used to tell solver that
it can stop after all eigenvalues converged with
error roughly proportional to eps*MAX(LAMBDA_MAX),
where LAMBDA_MAX is a maximum eigenvalue.
Zero value means that no check for precision is
performed.
MaxIts - maxits>=0, with non-zero value used to tell solver
that it can stop after maxits steps (no matter how
precise current estimate is)
NOTE: passing eps=0 and maxits=0 results in automatic selection of
moderate eps as stopping criteria (1.0E-6 in current implementation,
but it may change without notice).
NOTE: very small values of eps are possible (say, 1.0E-12), although the
larger problem you solve (N and/or K), the harder it is to find
precise eigenvectors because rounding errors tend to accumulate.
NOTE: passing non-zero eps results in some performance penalty, roughly
equal to 2N*(2K)^2 FLOPs per iteration. These additional computations
are required in order to estimate current error in eigenvalues via
Rayleigh-Ritz process.
Most of this additional time is spent in construction of ~2Kx2K
symmetric subproblem whose eigenvalues are checked with exact
eigensolver.
This additional time is negligible if you search for eigenvalues of
the large dense matrix, but may become noticeable on highly sparse
EVD problems, where cost of matrix-matrix product is low.
If you set eps to exactly zero, Rayleigh-Ritz phase is completely
turned off.

The algorithm finds eigenvalues and eigenvectors of a general matrix by
using the QR algorithm with multiple shifts. The algorithm can find
eigenvalues and both left and right eigenvectors.
The right eigenvector is a vector x such that A*x = w*x, and the left
eigenvector is a vector y such that y'*A = w*y' (here y' implies a complex
conjugate transposition of vector y).
Input parameters:
A - matrix. Array whose indexes range within [0..N-1, 0..N-1].
N - size of matrix A.
VNeeded - flag controlling whether eigenvectors are needed or not.
If VNeeded is equal to:
* 0, eigenvectors are not returned;
* 1, right eigenvectors are returned;
* 2, left eigenvectors are returned;
* 3, both left and right eigenvectors are returned.
Output parameters:
WR - real parts of eigenvalues.
Array whose index ranges within [0..N-1].
WR - imaginary parts of eigenvalues.
Array whose index ranges within [0..N-1].
VL, VR - arrays of left and right eigenvectors (if they are needed).
If WI[i]=0, the respective eigenvalue is a real number,
and it corresponds to the column number I of matrices VL/VR.
If WI[i]>0, we have a pair of complex conjugate numbers with
positive and negative imaginary parts:
the first eigenvalue WR[i] + sqrt(-1)*WI[i];
the second eigenvalue WR[i+1] + sqrt(-1)*WI[i+1];
WI[i]>0
WI[i+1] = -WI[i] < 0
In that case, the eigenvector corresponding to the first
eigenvalue is located in i and i+1 columns of matrices
VL/VR (the column number i contains the real part, and the
column number i+1 contains the imaginary part), and the vector
corresponding to the second eigenvalue is a complex conjugate to
the first vector.
Arrays whose indexes range within [0..N-1, 0..N-1].
Result:
True, if the algorithm has converged.
False, if the algorithm has not converged.
Note 1:
Some users may ask the following question: what if WI[N-1]>0?
WI[N] must contain an eigenvalue which is complex conjugate to the
N-th eigenvalue, but the array has only size N?
The answer is as follows: such a situation cannot occur because the
algorithm finds a pairs of eigenvalues, therefore, if WI[i]>0, I is
strictly less than N-1.
Note 2:
The algorithm performance depends on the value of the internal parameter
NS of the InternalSchurDecomposition subroutine which defines the number
of shifts in the QR algorithm (similarly to the block width in block-matrix
algorithms of linear algebra). If you require maximum performance
on your machine, it is recommended to adjust this parameter manually.
See also the InternalTREVC subroutine.
The algorithm is based on the LAPACK 3.0 library.

The source matrix A is represented as S'*A*S = T, where S is an orthogonal
matrix (Schur vectors), T - upper quasi-triangular matrix (with blocks of
sizes 1x1 and 2x2 on the main diagonal).

Output parameters:
A - contains matrix T.

S - contains Schur vectors.
Array whose indexes range within [0..N-1, 0..N-1].
Note 1:
The block structure of matrix T can be easily recognized: since all
the elements below the blocks are zeros, the elements a[i+1,i] which
are equal to 0 show the block border.
