I am using patternsearch algorithm to find minimum of a function (area of intersection of some objects). I know that the minimum cannot be less than 0, thus I want to stop when the function value is 0. How to do it?

Filip - are you using an algorithm from a MATLAB toolbox or something that you have written? Please provide a reference to that code.

Use an output function and set stop = true when the function value gets close enough to 0.
