Many thanks ! I now see my fundamental mistake was trying to include a
(non-existant) complex.h.

I had to mod the sqrt line by adding "std::" in front of the 'sqrt' - I only
mention this as having never used this kind of thing I thought I'd check that
this wasn't indicative of me having failed to do something else.

The majority of the project is C++ (MFC) but contains core analysis
algorithms that are straight C (for portability reasons).

Thanks for pointing me in the right direction,

TTFN,
