mkl_sparse_?_set_value

Changes a single value of matrix in internal representation.

Syntax

stat = mkl_sparse_s_set_value (A , row, col, value);

stat = mkl_sparse_d_set_value (A, row, col, value );

stat = mkl_sparse_c_set_value (A , row, col, value);

stat = mkl_sparse_z_set_value (A , row, col, 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

SPARSE_MATRIX_T.

Specifies handle containing internal data.

row

C_INT .

Indicates row of matrix in which to set value.

col

C_INT .

Indicates column of matrix in which to set value.

value

C_FLOAT for mkl_sparse_s_create_csr

C_DOUBLE for mkl_sparse_d_create_csr

C_FLOAT_COMPLEX for mkl_sparse_c_create_csr

C_DOUBLE_COMPLEX for mkl_sparse_z_create_csr

Indicates value

Output Parameters

A

Handle containing modified internal data.

<!-- -->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_INVALID_VALUE

The input parameters contain an invalid value.

SPARSE_STATUS_INTERNAL_ERROR

An error in algorithm implementation occurred.
