void
cublasDrot (int n, double *x, int incx, double *y, int incy, double sc,
double ss)

multiplies a 2x2 matrix ( sc ss) with the 2xn matrix ( transpose(x) )
(-ss sc)                     ( transpose(y) )

The elements of x are in x[lx + i * incx], i = 0 ... n - 1, where lx = 1 if
incx >= 0, else lx = 1 + (1 - n) * incx, and similarly for y using ly and
incy.

Input
-----
n      number of elements in input vectors
x      double-precision vector with n elements
incx   storage spacing between elements of x
y      double-precision vector with n elements
incy   storage spacing between elements of y
sc     element of rotation matrix
ss     element of rotation matrix

Output
------
x      rotated vector x (unchanged if n <= 0)
y      rotated vector y (unchanged if n <= 0)
