Extract Coefficients of Fourier Series


Hi All,

I have a set of points which have I fitted to a fourier serires with
the TrigFit function.  This gives me a fourier series.  What I want is
to extract all the coefficients of the series, square them, then sum
them.  How do I this (more specifically, the extraction step?

Thanks in advanced.
