Revival of a 14 years old code (written in 1991 for MATLAB 2.x).

Given a set of measured x,y pairs that a re supposed to reside on a circle, but with some added noise. A circle to these points, i.e. find xc,yc,R, such that (x-xc)^2+(y-yc)^2=R^2

The method minimizes the sum of squared radial deviations.
