Signature

def zrot(x, y, c, s, n = Ellipsis, offx = 0, incx = 1, offy = 0, incy = 1, overwrite_x = 0, overwrite_y = 0)

Apply a plane rotation to a pair of complex vectors (LAPACK zrot).

Only the complex flavors exist here; for real vectors this is BLAS rot.

x : ndarray: First vector.
y : ndarray: Second vector.
c : float: The cosine. Real even though the vectors are complex.
s : complex: The sine.
n : int, optional: How many elements to rotate. Default is as many as x allows from offx at stride incx.
offx : int, optional: Index in x to start from. Default is 0.
incx : int, optional: Stride through x. Default is 1.
offy : int, optional: Index in y to start from. Default is 0.
incy : int, optional: Stride through y. Default is 1.
overwrite_x : int, optional: If nonzero, x may be overwritten in place. Default is 0.
overwrite_y : int, optional: If nonzero, y may be overwritten in place. Default is 0.
