In communications and signal processing, it is frequently necessary to calculate the power of a signal. This can be done with a function like the following:
def magsq(z): """ Return the magnitude squared of the real- or complex-valued input. """ return z.real**2 + z.imag**2 A high percentage of the scripts that I write contain or import a function like this. It would be great if there were a built-in method in NumPy, preferably with a name like `magsq`, `mag2`, or `msq`. Phillip
