integer(kind(rocblas_status_success)) function rocblas_srot_batched_ (handle, n, x, incx, y, incy, c, s, batch_count)
 

Detailed Description

BLAS Level 1 API.

The rot_batched functions apply the Givens rotation matrix defined by c=cos(alpha) and s=sin(alpha) to batched vectors x_i and y_i, for i = 1, ..., batch_count. Scalars c and s can be stored in either host or device memory. The location is specified by calling rocblas_set_pointer_mode.

Parameters
[in]handle- [rocblas_handle] handle to the rocBLAS library context queue.
[in]n- [rocblas_int] number of elements in each x_i and y_i vectors.
[in,out]x- device array of device pointers storing each vector x_i.
[in]incx- [rocblas_int] specifies the increment between elements of each x_i.
[in,out]y- device array of device pointers storing each vector y_i.
[in]incy- [rocblas_int] specifies the increment between elements of each y_i.
[in]c- device pointer or host pointer to scalar cosine component of the rotation matrix.
[in]s- device pointer or host pointer to scalar sine component of the rotation matrix.
[in]batch_count- [rocblas_int] the number of x and y arrays, that is, the number of batches.
