Type "stats" on the command line and see what it is. Then change the last few lines to this:

stats
sortedStats=sort([stats.Contrast])
fprintf('\n sorted contrast values are:\n %d\n', sortedStats);

Note the brackets around stats.Contrast to turn it into an array. But why are you looping over m and n and just overwriting the same stats scalar over and over again? It needs to be indexed so you keep the separate values.
