Does anybody know where I can find code for a C function to fit

And last but not least: what made you post this in c.a._embedded_,
of all places?

It seems to me that this is a required technique for all sorts of
embedded systems. The area of differences will probably be in
selecting points for rejection (in the fitted samples), probabably
on the base of deviation from the fitted curve.
