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
confusionmat Compute confusion matrix for classification problem
perfcurve Receiver operating characteristic (ROC) curve or other performance curve for classifier output

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);
