Nonlinear fits

You can download here a small program to do nonlinear fits (polynomial, exponential, logarithmic, power, sinusoidal regressions).

Source (gzipped tar file, Unix)
Zipped executable (Windows)

I wrote it several years ago without having previously studied any serious mathematical regression theory, so it really doesn't work very well. Hopefully someone will find it useful.

Unix: To install the program, simply uncompress it with tar -xzf fits.tar.gz Then go into the subdirectory mathlib/fits and type make
Windows: To install the programm, first uncompress it with any zipper/unzipper (find one here). It is then ready-to-use.
