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

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. |
|
alpha |
Input |
Pointer to scalar α used for executing the multiplication operation. |
|
a |
Input |
Pointer to matrix A. |
|
lda |
Input |
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 |
Input |
Pointer to vector x. |
|
incx |
Input |
Increment between successive x elements. This parameter is reserved and can only be set to –1. |
|
beta |
Input |
Pointer to scalar β used for executing the multiplication operation. |
|
y |
Input/Output |
Pointer to vector y. |
|
incy |
Input |
Increment between successive y elements. This parameter is reserved and can only be set to –1. |
|
type |
Input |
Computation precision type (high precision by default). |
|
stream |
Input |
Stream where the operator is executed. |
Returns
0 on success; else, failure. For details, see aclError.
