[Numpy-discussion] python numpy code many times slower than c++

I tried a little experiment, implementing some code in numpy (usually I
build modules in c++ to interface to python). Since these operations are
all large vectors, I hoped it would be reasonably efficient.
The code in question is simple. It is a model of an amplifier, modeled by
it's AM/AM and AM/PM characteristics.
The function in question is the __call__ operator. The test program plots a
spectrum, calling this operator 1024 times each time with a vector of 4096.
Any ideas? The code is not too big, so I'll try to attach it.
