NumericalTransferFunction:
-------------------------------------------------------------------------------
Computes a numerical transfer function from the impulse response for the system.
The response f must be sampled at uniform time intervals. This function uses
an fft but effectively it is integrating exp(-st)*f(t) dt from zero to infinity.
If the system is not damped, the results will be poor. For fastest results the
number of samples should be a power of two.
