Hi.
Thanks for a great binding!
I have built FANN 2.2.0, and generated the four mex functions.
Now I am struggling to get a sensible output when using createFann, trainFann and testFann. Please see the matlab commands and outputs below. Should not actualValues equal suggestedValues? Do you have any idea what I am doing wrong?

samples = [...
-1 -1
-1 1
1 -1
1 1];
actualValues = [...
-1
1
1
-1];

numVariables = size(samples,2);
numResults = size(actualValues,2);
connectivity = 1;
max_epochs = 500000;
desired_error = .0000001;
layers = [numVariables 3 5 numResults];

% makeFann;
ann = createFann(layers,connectivity);

ann = trainFann(ann,samples,actualValues,desired_error,max_epochs)

ann =

      layers: [2 3 5 1]
     weights: [35x1 double]
        from: [35x1 double]
          to: [35x1 double]
connectivity: 1

suggestedValues = testFann(ann,samples);

[actualValues suggestedValues]

ans =

-1.0000 0.0000
1.0000 0.0000
1.0000 0.0000
-1.0000 0.0000

suggestedValues =
