csc_zusadd() void csc_zusadd ( int  m, int  n, doublecomplex  alpha, const doublecomplex  val_a[], const int  colptr_a[], const int  rowind_a[], int  base_a, doublecomplex  beta, const doublecomplex  val_b[], const int  colptr_b[], const int  rowind_b[], int  base_b, doublecomplex  val_c[], int  colptr_c[], int  rowind_c[], int  base_c, int  nnz_c, int *  info  ) C <- αA + βB (Complex matrices) (CSC) Purpose This routine performs the following matrix-matrix operation for sparse matrices A, B and C in CSC format. C <- α*A + β*B where α and β are scalars (complex numbers), and A, B and C are m x n complex sparse matrices. Parameters [in] m Number of rows of the matrix. (m >= 0) (if m = 0, returns without computation) [in] n Number of columns of the matrix. (n >= 0) (if n = 0, returns without computation) [in] alpha Scalar alpha. [in] val_a[] Array val_a[l_val_a] (l_val_a >= nnz_a) (nnz_a is the number of nonzero elements of A) Values of nonzero elements of input matrix A. [in] colptr_a[] Array colptr_a[l_colptr_a] (l_colptr_a >= n + 1) Column pointers of input matrix A. [in] rowind_a[] Array rowind_a[l_rowind_a] (l_rowind_a >= nnz_a) (nnz_a is the number of nonzero elements of A) Row indices of input matrix A. [in] base_a Indexing of colptr_a[] and rowind_a[]. = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. [in] beta Scalar beta. [in] val_b[] Array val_b[l_val_b] (l_val_b >= nnz_b) (nnz_b is the number of nonzero elements of B) Values of nonzero elements of input matrix B. [in] colptr_b[] Array colptr_b[l_colptr_b] (l_colptr_b >= n + 1) Column pointers of input matrix B. [in] rowind_b[] Array rowind_b[l_rowind_b] (l_rowind_b >= nnz_b) (nnz_b is the number of nonzero elements of B) Row indices of input matrix B. [in] base_b Indexing of colptr_b[] and rowind_b[]. = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. [out] val_c[] Array val_c[l_val_c] Values of nonzero elements of output matrix C. [out] colptr_c[] Array colptr_c[l_colptr_c] (l_colptr_c >= n + 1) Column pointers of output matrix C. [out] rowind_c[] Array rowind_c[l_rowind_c] Row indices of output matrix C. [in] base_c Indexing of colptr_c[] and rowind_c[]. = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. [in] nnz_c Enter min(l_val_c, l_rowind_c). nnz_c must be not less than the number of nonzero elements of α*A + β*B. [out] info = 0: Successful exit. = i < 0: The (-i)-th argument is invalid. = j > 0: nnz_c is too small. Exceeded during computing j-th column.
