SnapMatrixToSparsityPattern Subroutine

public subroutine SnapMatrixToSparsityPattern(mat, pattern)

Some codes use a fixed sparsity pattern for a matrix instead of filtering small values. Using this routine, the matrix is filled to have the same pattern as the second matrix argument. Zeros of the sparsity pattern are left in, whereas values outside the sparsity are removed. This can faciliate conversion between formats.

Arguments

Type	Intent	Optional	Attributes		Name
type(Matrix_ps),	intent(inout)			::	mat	The matrix to modify.
type(Matrix_ps),	intent(in)			::	pattern	The matrix which defines the sparsity pattern.
