confusionmat

Hi, here you have my implementation of the confusionmat function. I hope it helps someone

 function [ret] = confusionmat(v1, v2)
    values = union(unique(v1), unique(v2));
    ret = zeros(size(values), size(values));
    for i = 1:size(v1)
       i1 = find(values == v1(i));
       i2 = find(values == v2(i));
       ret(i1, i2) = ret(i1, i2) + 1;
    end
 endfunction
