Minimum Enclosing Circle

This code takes an input of a set of given (x,y) points in the Cartesian coordinates and returns the center and radius of the minimum circle enclosing the points.

This code is based on that of Yazan Ahed, and contains no changes in the algorithm but only in the structure.

The previous code was written based on the very nice Java applet found here: http://heyoka.cs.uiuc.edu/~thite/mincircle/
Credit are due mainly to author of the applet.
