Parameters
alphafloat

The scalar .

xcomplex, array-like, shape

The -element vector .

Returns
ycomplex, ndarray, shape

The elements of the vector .

Notes

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

zdaxpzy performs the operation

where and are -element complex vectors, and is a real scalar.
