dlalg_pseudo_inverse()

subroutine lalg_adv_oct_m::lalg_pseudo_inverse::dlalg_pseudo_inverse ( real(real64), dimension(:, :), intent(inout), allocatable  a, real(real64), intent(in), optional  threshold  )

private

Invert a matrix with the Moore-Penrose pseudo-inverse.

SVD is used to find the U, V and Sigma matrices:

\[ A = U \Sigma V^\dagger \]

Diagonal terms in Sigma <= threshold are set to zero, and the inverse is constructed as:

\[] A^{-1} \approx V \Sigma U^\dagger \]

Parameters

[in,out]

a

Input: (m, n)
