I need an algorithm to fit a set of data points, obtained
experimentally, to the best-fit circle.  I have searched through many
book son least squares anaylsis, but can only find simple cases.  I
started to do the math, but it became rather involved very quickly.

I would appreciate it if i can get code to do this, or perhaps leads
as to where I can continue looking.

Thanks in advance....
