Serial port to Matlab

Hi, I found the code below which I intend to use for plotting real-time analog data from a microcontroller. How can I modify the code so that I can plot five analog signals instead of just one? I know that I have to change dat = fscanf(s,'%f'); to dat = fscanf(s,'%f,%f,%f,%f,%f'); I also replaced data(count) = dat(1); with data(count,:) = dat'; but unfortunately it is not working. Any kind of help would be highly appreciated.
