PCA is used for dimensionality reduction and to help you visualise higher dimensional data. On its own it is not a classification tool. If you have access to the Statistics Toolbox then you can use the "classify" function which runs discriminant analyses. I suggest you work through the example in the help and then see if you can apply it to your data: http://www.mathworks.co.uk/help/stats/classify.html
