I'm using classification learner app to classify a 6 class data-set. The app is able to train the data and display over all accuracy but it is unable to display the individual class accuracies in the confusion matrix. It just displays the confusion matrix with empty boxes.

Hi,

From Classification Learner App try to export the trained model to work space and use the in built MATLAB function "confusionmat" for confusion matrix. Enjoy playing with MATLAB :)
