Did you mean `np.square`? Sadly, that doesn't do the right thing: `np.square(1+1j)` yields `2j`, while one wants `c*c.conj()` and thus `2`. Or, for fastest speed, really just `c.real**2 + c.imag**2`. My guess would be that a new ufunc, say `np.abs2` or `np.modulus2` or so, would be more appropriate than defining a new method. I'd also be hesitant to define a new private method -- I like how those usually are just used to override python basics. -- Marten
