jpg image capture using webcam in matlab gui

I built a gui wherein i can view a runtime video and capture image using data on http://www.mathworks.in/support/solutions/en/data/1-1CBPW/

using the code on the link image is saved in .mat format whereas I require it in .jpg format.

I tried replacing 'testframe.mat' by 'testframe.jpg' in the captureImage_Callback(hObject, eventdata, handles) function but it doesnt work,although file "testframe.jpg" is saved in the workspace it doesnt open

how can I save the frame in jpg format
