- 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,
