I need curve fitting routine (or even an algorithm that is
known to work) that will fit data to a 2 or 3 harmonic 
cosine wave with the amplitude and phase of each harmonic.

I would rather use a routine that is written specifically for
this case than apply a general nonlinear fitter.

Thanks in advance,

John Hudson
