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.

Maximum likelihood function

Recently, both to return to my old love for evolution and to broaden my research horizon, I have started working on models simulating the dynamics of evolutionary processes. It is becoming clearer and clearer in biology that to understand form,
