mkl_sparse_?_set_value

Changes a single value of matrix in internal representation.

Syntax

sparse_status_t mkl_sparse_s_set_value (const sparse_matrix_t A, const MKL_INT row, const MKL_INT col, const float value);

sparse_status_t mkl_sparse_d_set_value (const sparse_matrix_t A, const MKL_INT row, const MKL_INT col, const double value);

sparse_status_t mkl_sparse_c_set_value (const sparse_matrix_t A, const MKL_INT row, const MKL_INT col, const MKL_Complex8 value);

Description

Use the mkl_sparse_?_set_value routine to change a single value of a matrix in the internal Inspector-executor Sparse BLAS format. The value should already be presented in a matrix structure.

Input Parameters
A

Specifies handle containing internal data.

row

Indicates row of matrix in which to set value.

col

Indicates column of matrix in which to set value.

value

Indicates value

Output Parameters
A

Handle containing modified 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_INVALID_VALUE

The input parameters contain an invalid value.

SPARSE_STATUS_INTERNAL_ERROR

An error in algorithm implementation occurred.
