How did you train your classifier.
The following functions will help you. check documentations for more details
confusionchart Create confusion matrix chart for classification problem

If you have true classes and predicted classes, you can create confusion matrix from it
c = confusionmat(true,predicted);
and find the accuracy using
accuracy = sum(diag(c))/sum(c);
