??? Error using ==> reshape To RESHAPE the number of elements must not change.

Error in ==> sym_rec_img_preprocess at 32 Ibox = reshape(Ibox,[4 ((sizer*sizec)/noimages)]);

Error in ==> sym_rec_main2 at 78 img = sym_rec_img_preprocess(I, sizer, sizec,noimages);

sizer = size3Dr; %32
sizec = size3Dc;
noimages = sizer/6;  
   I = I3Dtotal(:,:,i);
    img = sym_rec_img_preprocess(I, size3Dr, size3Dc, noimages); % line 78

what am i doing wrong?

Go into sym_rec_img_preprocess and put these right before line 32:

size(Ibox)
size(sizer)
size(sizec)
noimages

Then tell us what the output to the command window says.

In the code sym_rec_img_preprocess, you are trying to use RESHAPE to reshape the variable Ibox to a size that is incompatible with the original size of Ibox. Try putting in a breakpoint on line 32 of sym_rec_img_preprocess and determine the size of Ibox as well as the size of (sizer*sizec)/noimages, you will see that:

4*(sizer*sizec)/noimages ~= numel(Ibox)

yes that 's what i did. is it possible if i send you the program? becaus I can't seem to do it write. When I eliminate all the errors it start again from the first one!
