Detailed Description

BLAS Level 1 API.

The copyStridedBatched functions copy each element x_i[j] into y_i[j], for j = 1 , ... , n; i = 1 , ... , batchCount.

y_i := x_i,

where (x_i, y_i) is the i-th instance of the batch. x_i and y_i are vectors.

• Supported precisions in rocBLAS : s, d, c, and z.
• 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 to be copied to y_i.
[in]	x	- device pointer to the first vector (x_1) in the batch.
[in]	incx	- [int] specifies the increments for the elements of vectors 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.
[out]	y	- device pointer to the first vector (y_1) in the batch.
[in]	incy	- [int] specifies the increment for the elements of vectors 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 an appropriate size. For a typical case this means stridey >= n * incy. stridey should be non zero.
[in]	batchCount	- [int] number of instances in the batch.
