Hi, I am trying to test the results of a fitcsvm model, as shown below:

    SVM_1_2 = fitcsvm(training_space,labels);
    [label,score] = predict(SVM_1_2,space);

Where training_space is a sub_space of the total space. label is always an array full of zero, even for the points in training_space

I do not understand why predict is not giving me the predicted class of all the points in space. Can anyone help me, please?

It's pretty difficult to help here, without the data. Can you upload the data (or a small sample that shows the same problem) in a MAT file?
