Computes matrix-vector multiplication: y = αAx + βy. The inputs and outputs are all of data type aclFloat16. This API is asynchronous.

trans_a: int, whether matrix A is transposed.

m: int, number of rows in matrix A (row-major first in data storing).

n: int, number of columns in matrix A.

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

a: int, data pointer address of matrix A.

lda: int, leading dimension of matrix A. For row-major transpose, lda is the number of columns of matrix A. This parameter is reserved and can only be set to –1.

x: int, data pointer address of vector x.

incx: int, increment between successive x elements. This parameter is reserved and can only be set to –1.

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

y: int, data pointer address of vector y.

incy: int, increment between successive y elements. This parameter is reserved and can only be set to –1.

type: int, calculation precision.

stream: int, stream where the operator is executed.

ret: int, error code.

• 0 indicates success.
• Other values indicate failure.
