dmatrix_rank_svd()

integer function lalg_adv_oct_m::lalg_matrix_rank_svd::dmatrix_rank_svd ( real(real64), dimension(:, :), intent(inout)  a, logical, intent(in), optional  preserve_mat, real(real64), intent(in), optional  tol  )

private

Compute the rank of the matrix A using SVD.

The rank is equal to the number of non-zero singular values in the diagonal matrix of the SVD decomposition.

Parameters

[in,out]	a	Input: (m, n)
[in]	preserve_mat	Preserve input A
[in]	tol	Tolerance defining

Returns

Rank of matrix A

zmatrix_rank_svd()

integer function lalg_adv_oct_m::lalg_matrix_rank_svd::zmatrix_rank_svd ( complex(real64), dimension(:, :), intent(inout)  a, logical, intent(in), optional  preserve_mat, real(real64), intent(in), optional  tol  )

private

Compute the rank of the matrix A using SVD.

The rank is equal to the number of non-zero singular values in the diagonal matrix of the SVD decomposition.

Parameters

[in,out]	a	Input: (m, n)
[in]	preserve_mat	Preserve input A
[in]	tol	Tolerance defining

Returns

Rank of matrix A
