3D data cumsum does not work

Hello all,

I have a 3D data like 2532X3542X26. I combined 26 number of 2D data 2532X3542 because of some reason. So now, I want to sum of the all matrices like following:

qq(:,:,1)=R(:,:,1);

qq(:,:,2)=R(:,:,1)+R(:,:,2);

qq(:,:,3)=R(:,:,1)+R(:,:,2)+R(:,:,3);

qq(:,:,4)=R(:,:,1)+R(:,:,2)+R(:,:,3)+R(:,:,4);

qq(:,:,5)=R(:,:,1)+R(:,:,2)+R(:,:,3)+R(:,:,4)+R(:,:,5);

qq(:,:,6)=R(:,:,1)+R(:,:,2)+R(:,:,3)+R(:,:,4)+R(:,:,5)+R(:,:,6);

qq(:,:,7)=R(:,:,1)+R(:,:,2)+R(:,:,3)+R(:,:,4)+R(:,:,5)+R(:,:,6)+R(:,:,7);

qq(:,:,8)=R(:,:,1)+R(:,:,2)+R(:,:,3)+R(:,:,4)+R(:,:,5)+R(:,:,6)+R(:,:,7)+R(:,:,8);

qq(:,:,9)=R(:,:,1)+R(:,:,2)+R(:,:,3)+R(:,:,4)+R(:,:,5)+R(:,:,6)+R(:,:,7)+R(:,:,8)+R(:,:,9);

.

.

until qq(:,:,26)=R(:,:,1)+R(:,:,2)+R(:,:,3)+R(:,:,4)+R(:,:,5)+R(:,:,6)+R(:,:,7)+R(:,:,8)+R(:,:,9)+......+R(:,:,26);

Please help me another way to do it. I do not use like a this way. I need a for loop but I could not achieve it correctly. Thanks all

Oh. So it does not work if you do this?

qq = cumsum(rr,3);

I guess you should report that as a bug, because it works for me. I wonder why it fails for you? :)

Oh sorry, I see. Thank you so much.
