function playMovie(filename)

obj = mmreader(filename);
vidFrames = read(obj);
numFrames = get(obj, 'numberOfFrames');
% reading each frame
for k=1:numFrames
    img(k).cdata = vidFrames(:,:,:,k);
    img(k).colormap = [];
end
 % Playing the movie
movie(img, obj.FrameRate);

% displying a move frame
%f = fix(numFrames/2);
%imagesc(img(f).cdata);

for m=1:numFrames
    z=img(m).cdata-img(m+1).cdata;
    z(numFrames)
end

end

Hello guys, this code hopefully will subtract the image from the previous one. This code gives an error at the very beginning, while the function suppose the ask me a video file it gives an error. I could not understand why.
Thank you for help

I don't think we have any matlab programmers on the forum. That said, have you used output statements to isolate which line is causing the problem?
