Detailed Description
BLAS Level 1 API.
The copy_strided_batched functions copy each element x_i[j] into y_i[j], for j = 1 , ... , n; i = 1 , ... , batch_count:
y_i := x_i,
where (x_i, y_i) is the i-th instance of the batch and x_i and y_i are vectors.
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in] n - [rocblas_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 - [rocblas_int] specifies the increments for the elements of vectors x_i. [in] stridex - [rocblas_stride] 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, ensure that stride_x is of an appropriate size. For a typical case, this means stride_x >= n * incx. [out] y - device pointer to the first vector (y_1) in the batch. [in] incy - [rocblas_int] specifies the increment for the elements of vectors y_i. [in] stridey - [rocblas_stride] stride from the start of one vector (y_i) and the next one (y_i+1). There are no restrictions placed on stride_y, However, ensure that stride_y is of an appropriate size. For a typical case, this means stride_y >= n * incy. stridey should be non zero. [in] batch_count - [rocblas_int] number of instances in the batch.
