This is the code:
setDir = fullfile(toolboxdir('vision'),'visiondata','imageSets');
imds = imageDatastore('C:\Users\JIARA\Documents\MainGUI\Eye Images\*.jpg');
[trainingSet,testSet] = splitEachLabel(imds,0.3,'randomize');
bag = bagOfFeatures(trainingSet);
categoryClassifier = trainImageCategoryClassifier(trainingSet,bag);
confMatrix = evaluate(categoryClassifier,testSet);

imageDatastore objects were introduced in R2015b, but imageDatastore() did not become a callable function until R2016a.
