dmatrix_norm2()

subroutine lalg_adv_oct_m::lalg_matrix_norm2::dmatrix_norm2 ( integer, intent(in)  m, integer, intent(in)  n, real(real64), dimension(:, :), intent(inout), contiguous  a, real(real64), intent(out)  norm_l2, logical, intent(in), optional  preserve_mat  )

private

Norm of a 2D matrix.

The spectral norm of a matrix \(A\) is the largest singular value of \(A\). i.e., the largest eigenvalue of the matrix \(\sqrt{\dagger{A}A}\).

Parameters

[in]	m,n	Dimensions of A
[in]	a	2D matrix
[out]	norm2	L2 norm of A
