Function Usage

Creates a handle to matrix-vector multiplication. The data types of the input and output data are set using arguments. After the handle is created, call aclopExecWithHandle to execute the operator.

A, x, and y support a limited combination of data types.

Data Type of A	Data Type of x	Data Type of y
FLOAT16	FLOAT16	FLOAT16
FLOAT16	FLOAT16	FLOAT
INT8	INT8	FLOAT
INT8	INT8	INT32

Parameters

Parameter	Input/Output	Description
transA	Input	Transpose flag of matrix A. For details about the type definition, see aclTransType.
m	Input	Number of rows in matrix A (row-major first in data storing).
n	Input	Number of columns in matrix A.
dataTypeA	Input	Data type of matrix A. For the type definition, see aclDataType.
dataTypeX	Input	Data type of vector x. For the type definition, see aclDataType.
dataTypeY	Input	Data type of vector y. For the type definition, see aclDataType.
type	Input	Computation precision type (high precision by default). For details about the type definition, see aclComputeType.
handle	Output	Pointer to the operator execution handle's pointer. For details about the type definition, see aclopHandle.

Returns

0 on success; else, failure. For details, see aclError.
