	Initializes the algorithm selection descriptor.
hipsparseStatus_t	hipsparseLtMatmulAlgSetAttribute (const hipsparseLtHandle_t handle, hipsparseLtMatmulAlgSelection_t algSelection, hipsparseLtMatmulAlgAttribute_t attribute, const void *data, size_t dataSize)
	Specify the algorithm attribute of a algorithm selection descriptor.
hipsparseStatus_t	hipsparseLtMatmulAlgGetAttribute (const hipsparseLtHandle_t handle, const hipsparseLtMatmulAlgSelection_t algSelection, hipsparseLtMatmulAlgAttribute_t attribute, void *data, size_t dataSize)

Provides algorithms for matrix multiply

hipsparseStatus_t hipsparseLtMatmulAlgGetAttribute	(	const hipsparseLtHandle_t *	handle,
		const hipsparseLtMatmulAlgSelection_t *	algSelection,
		hipsparseLtMatmulAlgAttribute_t	attribute,
		void *	data,
		size_t	dataSize )

Get the specific algorithm attribute from algorithm selection descriptor.

hipsparseLtMatmulAlgGetAttribute returns the value of the queried attribute belonging to algorithm selection descriptor.

Parameters

[in]	handle	the hipsparselt handle
[in]	algSelection	the algorithm selection descriptor
[in]	attribute	attributes are specify in hipsparseLtMatmulAlgAttribute_t
[in,out]	data	the memory address containing the attribute value retrieved by this function
[in]	dataSize	size in bytes of the attribute value used for verification.

Return values

HIPSPARSE_STATUS_SUCCESS	the operation completed successfully.
HIPSPARSE_STATUS_INVALID_VALUE	`handle` , `algSelection` , `attribute` , `data` or `dataSize` is invalid.
HIPSPARSE_STATUS_NOT_SUPPORTED	`attribute` is not supported.

hipsparseStatus_t hipsparseLtMatmulAlgSelectionInit	(	const hipsparseLtHandle_t *	handle,
		hipsparseLtMatmulAlgSelection_t *	algSelection,
		const hipsparseLtMatmulDescriptor_t *	matmulDescr,
		hipsparseLtMatmulAlg_t	alg )

Initializes the algorithm selection descriptor.

hipsparseLtMatmulAlgSelectionInit creates a algorithm selection descriptor.

Parameters

[in]	handle	the hipsparselt handle

[in]	alg	the algorithm used to do the matrix multiplication.

Return values

HIPSPARSE_STATUS_SUCCESS	the operation completed successfully.
HIPSPARSE_STATUS_INVALID_VALUE	`handle` , `matmulDescr` or `algSelection` is invalid.

hipsparseStatus_t hipsparseLtMatmulAlgSetAttribute	(	const hipsparseLtHandle_t *	handle,
		hipsparseLtMatmulAlgSelection_t *	algSelection,
		hipsparseLtMatmulAlgAttribute_t	attribute,
		const void *	data,
		size_t	dataSize )

Specify the algorithm attribute of a algorithm selection descriptor.

hipsparseLtMatmulAlgSetAttribute sets the value of the specified attribute belonging to algorithm selection descriptor.

Parameters

[in]	handle	the hipsparselt handle
[in,out]	algSelection	the algorithm selection descriptor
[in]	attribute	attributes are specify in hipsparseLtMatmulAlgAttribute_t
[in]	data	pointer to the value to which the specified attribute will be set.
[in]	dataSize	size in bytes of the attribute value used for verification.

Return values

HIPSPARSE_STATUS_SUCCESS	the operation completed successfully.
HIPSPARSE_STATUS_INVALID_VALUE	`handle` , `algSelection` , `attribute` , `data` or `dataSize` is invalid.
HIPSPARSE_STATUS_NOT_SUPPORTED	`attribute` is not supported.
