[Dev-C++] Curve fitting C++

[Peter H. <pet...@ho...>]

I have a few points on a graph, and would like a C++ function that 
calculates a best fit equation such as a n degree polynomial.

Are there functions already available to do this, or any ideas how I would 
write one.
I've checked on the web but can't seem to find anything useful.

Thanks,
Pete
