options = gaoptimset('PlotFcns',@gaplotbestf);
x= ga(@f,6,[],[],[],[],[],[],[],options)

function gademo
    options= gaoptimset('PlotFcns',@myplot,'PopulationSize',10);
    x= ga(@f,6,[],[],[],[],[],[],[],options)

    function y= f(x) % the fitness function
        y= norm(x);
    end
        % simple plot function
    function state= myplot(options,state,flag)
        fprintf('generation number: %d\n',state.Generation);
        fprintf('population:\n');
        disp(state.Population);
    end
end

fprintf(1,'%f\n', x(1))
