mkl_sparse_convert_csr

Converts internal matrix representation to CSR format.

Syntax

sparse_status_t mkl_sparse_convert_csr (const sparse_matrix_t source, const sparse_operation_t operation, sparse_matrix_t *dest);

Include Files

  • mkl_spblas.h

Description

The mkl_sparse_convert_csr routine converts internal matrix representation to CSR format.

When the source matrix is in COO format, the routine performs a sum reduction on duplicate elements.

Input Parameters

source

Handle containing internal data.

operation

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.

Output Parameters

dest

Handle containing internal data.

Return Values

The function returns a 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.
