What is the equivalence of vid.FramesPerTrigger for frame acquisition in MATLAB 2016?

vid is the videoinput object I created in MATLAB 2013. I set the number of frames I want to acquire using vid.FramesPerTrigger. In MATLAB 2016, the equivalent form of videoinput is webcam. I want to know how to set the number of frames per trigger like I did for the videoinput object but this time with the webcam object. Also, what function should I use in order to set the frame rate of the webcam object in matlab 2016? vid.FrameRate is not working. It says: 'No appropriate method, property, or field 'FrameRate' for class 'webcam'.'

Please help me. Thank you very much.
