how to evaluate weka model in matlab

My code is javaaddpath('C:\Program Files\Weka-3-7\weka.jar'); import weka.classifiers.*; import weka.classifiers.Classifier.*; import weka.classifiers.Evaluation.* classifier = weka.classifiers.functions.MultilayerPerceptron; modelfiles = strcat(DatabasePath,'\','*','.model'); files = dir(modelfiles); filename=files(i).name; modelfilename = fullfile(DatabasePath, filename); cls = weka.core.SerializationHelper.read(modelfilename);

Now, how do I test a test file with cls in matlab?
