If you want to read in the last frame of a .asf file using mmread(), you can read in the entire file, but this can be very slow or cause Matlab to run out of memory.

You can read in only the last frame using mmread(), but to do this, you need to know the number of frames in the file.

mmcount() counts the number of frames in the file, after which mmread() can be used to read in the final frame. The time taken to count the frames and read in the final frame is much less than the time taken to read in the entire file with mmread().

mmcount() makes use of mmread() itself to do the counting.
