void
csrot (int n, cuComplex *x, int incx, cuCumplex *y, int incy, float c,
float s)

multiplies a 2x2 rotation matrix ( c s) with a 2xn matrix ( transpose(x) )
(-s c)                   ( 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      single-precision complex vector with n elements
incx   storage spacing between elements of x
y      single-precision complex vector with n elements
incy   storage spacing between elements of y
c      cosine component of rotation matrix
s      sine component of rotation matrix

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