    % generate input data on a grid
    [u1g u2g] = meshgrid(linspace(0,1,10), linspace(0,1,10));
    u1 = u1g(:);
    u2 = u2g(:);
    input = [u1 u2];

    % transformation for a good input space
    u1f = u1*15-5;
    u2f = u2*15;

    % Branin function
    output = (u2f-(5.1/(4*pi^2))*u1f.^2 + 5*u1f/pi-6).^2 + 10*(1-1/(8*pi))*cos(u1f)+10;

    % add some noise
    output = output + 0.1*randn(size(output))*(max(output)-min(output));

    % start training
    [LMNBest AllLMN] = LMNTrain([input output]);
