| integer(kind(rocblas_status_success)) function | rocblas_axpy_strided_batched_ex_ (handle, n, alpha, alpha_type, x, x_type, incx, stridex, y, y_type, incy, stridey, batch_count, execution_type) |
Detailed Description
BLAS EX API.
axpy_strided_batched_ex computes ant alpha multiplied by vector x, plus vector y over a set of strided batched vectors.
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 each x_i and y_i. [in] alpha device pointer or host pointer to specify the scalar alpha. [in] alpha_type [rocblas_datatype] specifies the datatype of alpha. [in] x device pointer to the first vector x_1. [in] x_type [rocblas_datatype] specifies the datatype of each vector x_i. [in] incx [rocblas_int] specifies the increment for the elements of each x_i. [in] stridex [rocblas_stride] stride from the start of one vector (x_i) to the next one (x_i+1). There are no restrictions placed on stridex, however the user should take care to ensure that stridex is of appropriate size, for a typical case this means stridex >= n * incx. [in,out] y device pointer to the first vector y_1. [in] y_type [rocblas_datatype] specifies the datatype of each vector y_i. [in] incy [rocblas_int] specifies the increment for the elements of each y_i. [in] stridey [rocblas_stride] stride from the start of one vector (y_i) to the next one (y_i+1). There are no restrictions placed on stridey, however the user should take care to ensure that stridey is of appropriate size, for a typical case this means stridey >= n * incy. [in] batch_count [rocblas_int] number of instances in the batch. [in] execution_type [rocblas_datatype] specifies the datatype of computation.
