Hi,
Sorry the Confusion matrix is not send in output of classifiers box. But you have a box confusion matrix who make that for you. You have just to set in left arrow the expected class, in right the result and set in your box the label (stimulation name) of each class

(An other boring solution is to install (with setup an old version 2.2.0 for example) setting your box next ope...

The compute of eigen value can be multiply by -1 between matlab and Eigen (our C++ Library) and order if it's in ascend or des...

Hi, I have already make that and 2 solution can be used : as thomas say you can implement a box c++ or python or an other possibility. If you HAve a simple DSP with only A - (B + 3*C). If you use an xml setting (you can save box option in an xml) You have to make a python script to modify the B and ...
