Description
The
mkl_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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
