mkl_sparse_spmm
Computes the product of two sparse matrices. The result is stored in a newly allocated sparse matrix.
Syntax
stat = mkl_sparse_spmm (operation, A, B, C)
Include Files
- mkl_spblas.f90
Description
The mkl_sparse_spmm routine performs a matrix-matrix operation:
C := op(A) *B
where A, B, and C are sparse matrices and op is a matrix modifier for matrix A.
- This routine is supported only for sparse matrices in CSC, CSR, and BSR formats. It is not supported for sparse matrices in COO format.
- The column indices of the output matrix (if in CSR format) can appear unsorted due to the algorithm chosen internally. To ensure sorted column indices (if that is important), call mkl_sparse_order().
Input Parameters
- operation
-
C_INT.
Specifies operation op() on input matrix.
SPARSE_OPERATION_NON_TRANSPOSE
Non-transpose, op(A) = A.
SPARSE_OPERATION_TRANSPOSE
Transpose, op(A) = AT.
SPARSE_OPERATION_CONJUGATE_TRANSPOSE
Conjugate transpose, op(A) = AH.
- A
-
SPARSE_MATRIX_T.
Handle which contains the sparse matrix A.
- B
-
SPARSE_MATRIX_T.
Handle which contains the sparse matrix B.
Output Parameters
- C
-
SPARSE_MATRIX_T.
Handle which contains the resulting sparse matrix.
- stat
-
INTEGER
Value indicating whether the operation was successful or not, and why:
SPARSE_STATUS_SUCCESS
The operation was successful.
SPARSE_STATUS_NOT_INITIALIZED
The routine encountered an empty handle or matrix array.
SPARSE_STATUS_ALLOC_FAILED
Internal memory allocation failed.
SPARSE_STATUS_INVALID_VALUE
The input parameters contain an invalid value.
SPARSE_STATUS_EXECUTION_FAILED
Execution failed.
SPARSE_STATUS_INTERNAL_ERROR
An error in algorithm implementation occurred.
SPARSE_STATUS_NOT_SUPPORTED
The requested operation is not supported.
