Description

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
aclFloat16	aclFloat16	aclFloat16
aclFloat16	aclFloat16	float(float32)
int8_t	int8_t	float(float32)
int8_t	int8_t	int32_t

Prototype

aclError aclblasCreateHandleForGemvEx(aclTransType transA,
int m,
int n,
aclDataType dataTypeA,
aclDataType dataTypeX,
aclDataType dataTypeY,
aclComputeType type,
aclopHandle **handle)

Parameters

Parameter	Input/Output	Description
transA	Input	Transpose flag of matrix A.
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.
dataTypeX	Input	Data type of vector x.
dataTypeY	Input	Data type of vector y.
type	Input	Computation precision type (high precision by default).
handle	Output	Pointer to the pointer to the operator handle.

Returns

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