DESCRIPTION

Top

Here is a list of all the functions included in this module :

gsl_linalg_matmult
gsl_linalg_matmult_mod
gsl_linalg_exponential_ss
gsl_linalg_householder_transform
gsl_linalg_complex_householder_transform
gsl_linalg_householder_hm($tau, $v, $A) - This function applies the Householder matrix P defined by the scalar $tau and the vector $v to the left-hand side of the matrix $A. On output the result P A is stored in $A. The function returns 0 if it succeded, 1 otherwise.
gsl_linalg_householder_mh($tau, $v, $A) - This function applies the Householder matrix P defined by the scalar $tau and the vector $v to the right-hand side of the matrix $A. On output the result A P is stored in $A.
gsl_linalg_householder_hv($tau, $v, $w) - This function applies the Householder transformation P defined by the scalar $tau and the vector $v to the vector $w. On output the result P w is stored in $w.
gsl_linalg_householder_hm1
gsl_linalg_complex_householder_hm($tau, $v, $A) - Does the same operation than gsl_linalg_householder_hm but with the complex matrix $A, the complex value $tau and the complex vector $v.
gsl_linalg_complex_householder_mh($tau, $v, $A) - Does the same operation than gsl_linalg_householder_mh but with the complex matrix $A, the complex value $tau and the complex vector $v.
gsl_linalg_complex_householder_hv($tau, $v, $w) - Does the same operation than gsl_linalg_householder_hv but with the complex value $tau and the complex vectors $v and $w.
gsl_linalg_hessenberg_decomp($A, $tau) - This function computes the Hessenberg decomposition of the matrix $A by applying the similarity transformation H = U^T A U. On output, H is stored in the upper portion of $A. The information required to construct the matrix U is stored in the lower triangular portion of $A. U is a product of N - 2 Householder matrices. The Householder vectors are stored in the lower portion of $A (below the subdiagonal) and the Householder coefficients are stored in the vector $tau. tau must be of length N. The function returns 0 if it succeded, 1 otherwise.
gsl_linalg_hessenberg_unpack($H, $tau, $U) - This function constructs the orthogonal matrix $U from the information stored in the Hessenberg matrix $H along with the vector $tau. $H and $tau are outputs from gsl_linalg_hessenberg_decomp.
gsl_linalg_hessenberg_unpack_accum($H, $tau, $V) - This function is similar to gsl_linalg_hessenberg_unpack, except it accumulates the matrix U into $V, so that V' = VU. The matrix $V must be initialized prior to calling this function. Setting $V to the identity matrix provides the same result as gsl_linalg_hessenberg_unpack. If $H is order N, then $V must have N columns but may have any number of rows.
gsl_linalg_hessenberg_set_zero($H) - This function sets the lower triangular portion of $H, below the subdiagonal, to zero. It is useful for clearing out the Householder vectors after calling gsl_linalg_hessenberg_decomp.
gsl_linalg_hessenberg_submatrix
gsl_linalg_hessenberg
gsl_linalg_hesstri_decomp($A, $B, $U, $V, $work) - This function computes the Hessenberg-Triangular decomposition of the matrix pair ($A, $B). On output, H is stored in $A, and R is stored in $B. If $U and $V are provided (they may be null), the similarity transformations are stored in them. Additional workspace of length N is needed in the vector $work.
gsl_linalg_SV_decomp($A, $V, $S, $work) - This function factorizes the M-by-N matrix $A into the singular value decomposition A = U S V^T for M >= N. On output the matrix $A is replaced by U. The diagonal elements of the singular value matrix S are stored in the vector $S. The singular values are non-negative and form a non-increasing sequence from S_1 to S_N. The matrix $V contains the elements of V in untransposed form. To form the product U S V^T it is necessary to take the transpose of V. A workspace of length N is required in vector $work. This routine uses the Golub-Reinsch SVD algorithm.
gsl_linalg_SV_decomp_mod($A, $X, $V, $S, $work) - This function computes the SVD using the modified Golub-Reinsch algorithm, which is faster for M>>N. It requires the vector $work of length N and the N-by-N matrix $X as additional working space. $A and $V are matrices while $S is a vector.
gsl_linalg_SV_decomp_jacobi($A, $V, $S) - This function computes the SVD of the M-by-N matrix $A using one-sided Jacobi orthogonalization for M >= N. The Jacobi method can compute singular values to higher relative accuracy than Golub-Reinsch algorithms. $V is a matrix while $S is a vector.
gsl_linalg_SV_solve($U, $V, $S, $b, $x) - This function solves the system A x = b using the singular value decomposition ($U, $S, $V) of A given by gsl_linalg_SV_decomp. Only non-zero singular values are used in computing the solution. The parts of the solution corresponding to singular values of zero are ignored. Other singular values can be edited out by setting them to zero before calling this function. In the over-determined case where A has more rows than columns the system is solved in the least squares sense, returning the solution x which minimizes ||A x - b||_2.
gsl_linalg_LU_decomp($a, $p) - factorize the matrix $a into the LU decomposition PA = LU. On output the diagonal and upper triangular part of the input matrix A contain the matrix U.

The function returns 1 if the operation succeded, 0 otherwise.
gsl_linalg_LU_refine($A, $LU, $p, $b, $x, $residual) - This function apply an iterative improvement to $x, the solution of $A $x = $b, using the LU decomposition of $A into ($LU,$p). The initial residual $r = $A $x - $b (where $x and $b are vectors) is also computed and stored in the vector $residual.

gsl_linalg_LU_det($LU, $signum) - This function returns the determinant of a matrix A from its LU decomposition stored in the $LU matrix. It needs the integer $signum which is the sign of the permutation returned by gsl_linalg_LU_decomp.
