integer(kind(hipblas_status_success)) function	hipblassscalstridedbatched_ (handle, n, alpha, x, incx, stridex, batchcount)
integer(kind(hipblas_status_success)) function	hipblassscalstridedbatched_rank_0 (handle, n, alpha, x, incx, stridex, batchcount)

Detailed Description

BLAS Level 1 API.

The scalStridedBatched functions scale 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.

• Supported precisions in rocBLAS : s, d, c, z, cs, and zd.
• Supported precisions in cuBLAS : No support.

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) to the next one (x_i+1). There are no restrictions placed on stride_x. However, the user should ensure that stride_x is of an appropriate size. For a typical case, this means stride_x >= n * incx.
[in]	batchCount	- [int] specifies the number of batches in x.
