Detailed Description

Computes the matrix sum: C = A + B, where the matrices are given in CSR format.

Parameters

[in]	nrow	The number of rows in the matrices.
[in]	ncol	The number of columns in the matrices.
[in]	a	The non-zero elements of matrix A.
[in]	ja	The column indices of matrix A.
[in]	ia	The index in A where the requested row starts.
[in]	b	The non-zero elements of matrix B.
[in]	jb	The column indices of matrix B.
[in]	ib	The index in B where the requested row starts.
[out]	c	The non-zero elements of matrix C.
[out]	jc	The column indices of matrix C.
[out]	ic	The index in C where the requested row starts.
[in]	nzmax	The length of arrays C & JC. The routine will stop if the results matrix C has a number of elements that exceeds NZMAX.
[out]	iw	A workspace array with a length equal to the number of of columns in matrix A.
[out]	ierr	An error message indicator. 0: Normal return .gt. 0: Routine failed in row I with IERR = I because the number of elements in C exceeds NZMAX.
