grid_image(v1:sx,v2:sy,k)=uint16(cell2mat(look(k,1)));%[1:sx,1:sy]
grid_overlap_number(v1:sx,v2:sy,k)=ones(sx,sy);

overlap_number=sum(grid_overlap_number(:,:,Nx*Ny*(l-1)+1:Nx*Ny*l),3);
slice_image= rdivide(overlap_image,overlap_number);
figure,imshow(uint8(slice_image));
end
toc;
when I run code the programme shows me
Index exceeds matrix dimensions.
Error in finalserialcode (line 28) v1=uint16(cell2mat(look(k,2)));
I cant figure it out.any one help?

Your variable look has a length of eleimg.
You are trying to access some value between 1 and Nx*Ny*L (which is equal to 98). I suspect that eleimg is smaller than 98.
