integer(kind(rocblas_status_success)) function rocblas_axpy_ex_ (handle, n, alpha, alpha_type, x, x_type, incx, y, y_type, incy, execution_type)
 

Detailed Description

BLAS EX API.

axpy_ex computes ant alpha multiplied by vector x, plus vector y

y := alpha * x + y

Currently supported datatypes are as follows:

-------------------------------------------------
| alpha_type | x_type | y_type | execution_type |
|------------|--------|--------|----------------|
|  f16_r     | f16_r  |  f16_r |      f16_r     |
|  f16_r     | f16_r  |  f16_r |      f32_r     |
|  f32_r     | f16_r  |  f16_r |      f32_r     |
|  f32_r     | f32_r  |  f32_r |      f32_r     |
|  f64_r     | f64_r  |  f64_r |      f64_r     |
|  f32_c     | f32_c  |  f32_c |      f32_c     |
|  f64_c     | f64_c  |  f64_c |      f64_c     |
-------------------------------------------------
Parameters
[in]handle[rocblas_handle] handle to the rocblas library context queue.
[in]n[rocblas_int] the number of elements in x and y.
[in]alphadevice pointer or host pointer to specify the scalar alpha.
[in]alpha_type[rocblas_datatype] specifies the datatype of alpha.
[in]xdevice pointer storing vector x.
[in]x_type[rocblas_datatype] specifies the datatype of vector x.
[in]incx[rocblas_int] specifies the increment for the elements of x.
[in,out]ydevice pointer storing vector y.
[in]y_type[rocblas_datatype] specifies the datatype of vector y.
[in]incy[rocblas_int] specifies the increment for the elements of y.
[in]execution_type[rocblas_datatype] specifies the datatype of computation.
