Detailed Description

BLAS Level 1 API.

rot_batched applies 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 may be stored in either host or device memory, 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]xdevice array of deivce pointers storing each vector x_i.
[in]incx[rocblas_int] specifies the increment between elements of each x_i.
[in,out]ydevice array of device pointers storing each vector y_i.
[in]incy[rocblas_int] specifies the increment between elements of each y_i.
[in]cdevice pointer or host pointer to scalar cosine component of the rotation matrix.
[in]sdevice pointer or host pointer to scalar sine component of the rotation matrix.
[in]batch_count[rocblas_int] the number of x and y arrays, i.e. the number of batches.
