I suggest a couple of minor changes :

1) Insert the following two lines after line 50 to get reasonable default values :

if (nargin < 3) winSize = 3; end;
if (nargin < 2) ord = 'med'; end;

2) Replace M = feature('memstats'); (which only works on Windows) with

try
    M = feature('memstats');
catch e
    M = 10^28; % or however many bytes of free space you figure your machine will have
end;

Very useful. I like the display of memory allocation. Is there a 3D median filter where the user can set unequal window sizes along the 3 directions?
