Computes matrix-matrix multiplication. The input and output data type is aclFloat16. It is an asynchronous interface.

C = αAB + βC

trans_a: int, whether matrix A is transposed.

trans_b: int, whether matrix B is transposed.

trans_c: int, transpose flag of matrix C. Currently, only aclTrans_N is supported.

m: int, number of rows in matrix A and C.

n: int, number of columns in matrix B and C.

k: int, number of columns in matrix A and number of rows in matrix B.

alpha: int, address of data pointer of Scalar alpha used for executing the multiplication operation.

matrix_a: int, address of data pointer of matrix A.

lda: int, leading dimension of matrix A. For row-major transpose, lda is the number of columns of matrix A.

matrix_b: int, address of data pointer of matrix B.

ldb: int, leading dimension of matrix B. For row-major transpose, leading dimension is the number of columns of matrix B.

beta: int, address of data pointer of Scalar β used for executing the multiplication operation.

matrix_c: int, address of data pointer of matrix C.

ldc: int, leading dimension of matrix C (reserved).

type: int, calculation precision.

stream: int, stream where the operator is executed.

ret: int, error code.

• 0 indicates success.
