Module Procedures

private subroutine AddSparseVectors_r(inner_index_a, values_a, inner_index_b, values_b, inner_index_c, values_c, total_values_c, alpha_in, threshold_in)

Add together two sparse vectors. C = A + alpha*B The values that are returned for C are only valid in the range (1:total_values_c). We do not do an automatic shrinking of the array to keep this routine low in overhead.

Arguments

Type	Intent	Optional	Attributes		Name
integer,	intent(in),		DIMENSION(:)	::	inner_index_a	List of indices for A.
real(kind=NTREAL),	intent(in),		DIMENSION(:)	::	values_a	List of values for A.
integer,	intent(in),		DIMENSION(:)	::	inner_index_b	List of indices for B.
real(kind=NTREAL),	intent(in),		DIMENSION(:)	::	values_b	List of values for B.
integer,	intent(out),		DIMENSION(:)	::	inner_index_c	List of indices for C.
real(kind=NTREAL),	intent(out),		DIMENSION(:)	::	values_c	List of values computed for C.
integer,	intent(out)			::	total_values_c	The total number of values in C.
real(kind=NTREAL),	intent(in),	optional		::	alpha_in	Value to scale VecB by. Optional, default is 1.0.
real(kind=NTREAL),	intent(in),	optional		::	threshold_in	for flushing values to zero. Default value is 0.0.
