| integer(kind(hipblas_status_success)) function | hipblasaxpystridedbatchedex_ (handle, n, alpha, alphatype, x, xtype, incx, stridex, y, ytype, incy, stridey, batchcount, executiontype) |
Detailed Description
BLAS EX API.
The axpyStridedBatchedEx functions compute a constant alpha multiplied by vector x, plus vector y, over a set of strided batched vectors.
y := alpha * x + y
The supported types are determined by the backend. See the rocBLAS or cuBLAS documentation.
- Parameters
-
[in] handle - [hipblasHandle_t] handle to the hipBLAS library context queue. [in] n - [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] alphaType [hipDataType] specifies the datatype of alpha. [in] x - device pointer to the first vector x_1. [in] xType [hipDataType] specifies the datatype of each vector x_i. [in] incx - [int] specifies the increment for the elements of each x_i. [in] stridex - [hipblasStride] 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 ensure that stridex is of an appropriate size. For a typical case, this means stridex >= n * incx. [in,out] y - device pointer to the first vector y_1. [in] yType [hipDataType] specifies the datatype of each vector y_i. [in] incy - [int] specifies the increment for the elements of each y_i. [in] stridey - [hipblasStride] 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 ensure that stridey is of appropriate size. For a typical case, this means stridey >= n * incy. [in] batchCount - [int] number of instances in the batch. [in] executionType [hipDataType] specifies the datatype of computation.
