Detailed Description

Contains utility routines for the active space module.

Function/Subroutine Documentation

subroutine, public qs_active_space_utils::subspace_matrix_to_array	(	type(cp_fm_type), intent(in)	source_matrix,
		real(kind=dp), dimension(:), intent(out)	target_array,
		integer, dimension(:), intent(in)	row_index,
		integer, dimension(:), intent(in)	col_index
	)

Copy a (square portion) of a cp_fm_type matrix to a standard 1D Fortran array.

Parameters

source_matrix	the matrix from where the data is taken
target_array	the array were the data is copied to
row_index	a list containing the row subspace indices
col_index	a list containing the column subspace indices
