Calculating region for inteligent classificator

Hello, I am using 3 classificators (Adaboost, HoKashyap and simple Perceptron) for classification patterns into two groups (1 and 0) acording to how they are trained. This is what i load (plot pattern on pattern)

And this is what i want it to look like (sort of)

So basically i need to make line boundaries acording to how succesfull the classifier was (how it split the data).

Pavel, you did not ask a MATLAB question ?
