The original vector .

yfloat, array-like, shape

The original vector .

cfloat

The value , the cosine of the rotation.

sfloat

The value , the sine of the rotation.

Returns
xfloat, ndarray, shape

The transformed vector .

yfloat, ndarray, shape

The transformed vector .

Notes

No equivalent traditional C interface for this routine exists in the NAG Library.
