Description

Creates a handle to matrix-matrix 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, B, and C support a limited combination of data types.

Data Type of A	Data Type of B	Data Type of C

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