Detailed Description

!

BLAS Level 1 API

\details
rot applies the Givens rotation matrix defined by c=cos(alpha) and s=sin(alpha) to vectors x and y.
    Scalars c and s may be stored in either host or device memory, location is specified by calling rocblas_set_pointer_mode.

@param[in]
handle  [rocblas_handle]
        handle to the rocblas library context queue.
@param[in]
n       [rocblas_int]
        number of elements in the x and y vectors.
@param[inout]
x       device pointer storing vector x.
@param[in]
incx    [rocblas_int]
        specifies the increment between elements of x.
@param[inout]
y       device pointer storing vector y.
@param[in]
incy    [rocblas_int]
        specifies the increment between elements of y.
@param[in]
c       device pointer or host pointer storing scalar cosine component of the rotation matrix.
@param[in]
s       device pointer or host pointer storing scalar sine component of the rotation matrix.
