apply_inverse_permutation_matrix Interface

public interface apply_inverse_permutation_matrix

Description

Given an array and a permutation vector , this function computes in-place the column-permuted matrix

where is the column-permutation matrix constructed from the permutation vector and its inverse.

Syntax

    call apply_inverse_permutation_matrix(X, perm)

Arguments

Q : Array of vectors derived from the base types defined in the AbstractVectors module. On entry, it is the original array. On exit, it contains the column-permuted version computed in-place. It is an intent(inout) argument.

perm : Rank-1 array of integer corresponding to the desired permutation vector. It is an intent(in) argument.
