Detailed Description
BLAS Level 1 API.
rot_strided_batched applies the Givens rotation matrix defined by c=cos(alpha) and s=sin(alpha) to strided 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] x device pointer to the first vector x_1. [in] incx [rocblas_int] specifies the increment between elements of each x_i. [in] stride_x [rocblas_stride] specifies the increment from the beginning of x_i to the beginning of x_(i+1) [in,out] y device pointer to the first vector y_1. [in] incy [rocblas_int] specifies the increment between elements of each y_i. [in] stride_y [rocblas_stride] specifies the increment from the beginning of y_i to the beginning of y_(i+1) [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, i.e. the number of batches.
