Description

Themkl_sparse_convert_bsr routine converts internal matrix representation to BSR format or changes BSR block size.

Input Parameters

source

Handle containing internal data.

block_size

Size of the block in the output structure.

block_layout

Specifies layout of blocks:

`SPARSE_LAYOUT_ROW_MAJOR`	Storage of elements of blocks uses row major layout.
`SPARSE_LAYOUT_COLUMN_MAJOR`	Storage of elements of blocks uses column major layout.

operation

Specifies operation op() on input matrix.

`SPARSE_OPERATION_NON_TRANSPOSE`	Non-transpose, `op(A) = A`.
`SPARSE_OPERATION_TRANSPOSE`	Transpose, `op(A) = A^T`.
`SPARSE_OPERATION_CONJUGATE_TRANSPOSE`	Conjugate transpose, `op(A) = A^H`.

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.
