scamac_sparsemat_check_symmetry()

ScamacErrorCode scamac_sparsemat_check_symmetry	(	const ScamacMatrix *	sm,
		bool *	symm_pattern,
		bool *	symm_value
	)

query symmetry (hermiticity) of matrix

Precondition

assumes ordered, i.e., monotonically increasing column indices. This is true for matrices obtained from the ScaMaC generators with scamac_sparsemat_from_generator()

Parameters

[in]	sm	sparse matrix to be checked
[out]	symm_pattern	Is the sparsity pattern symmetric?
[out]	symm_value	Is the matrix symmetric (for real sm) or Hermitian (for complex sm)?

Note

symm_pattern==false implies symm_value==false

Returns
