| 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.
