Detailed Description
BLAS Level 1 API.
The rot functions apply the Givens rotation matrix defined by c=cos(alpha) and s=sin(alpha) to vectors x and y. 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 the x and y vectors. [in,out] x - device pointer storing vector x. [in] incx - [rocblas_int] specifies the increment between elements of x. [in,out] y - device pointer storing vector y. [in] incy - [rocblas_int] specifies the increment between elements of y. [in] c - device pointer or host pointer storing the scalar cosine component of the rotation matrix. [in] s - device pointer or host pointer storing the scalar sine component of the rotation matrix.
