Detailed Description
BLAS Level 1 API.
scalStridedBatched scales each element of vector x_i with scalar alpha, for i = 1, ... , batchCount.
x_i := alpha * x_i ,
where (x_i) is the i-th instance of the batch.
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas library context queue. [in] n [int] the number of elements in each x_i. [in] alpha host pointer or device pointer for the scalar alpha. [in,out] x device pointer to the first vector (x_1) in the batch. [in] incx [int] specifies the increment for the elements of x. [in] stridex [hipblasStride] stride from the start of one vector (x_i) and the next one (x_i+1). There are no restrictions placed on stride_x, however the user should take care to ensure that stride_x is of appropriate size, for a typical case this means stride_x >= n * incx. [in] batchCount [int] specifies the number of batches in x.
