If you want an image the same size as img2 then
r = zeros(size(img2), class(img2));
after which you can assign ones into an appropriate section of r
Your phrase size(img2,2)/2 has a problem when the number of columns in img2 is odd, as it does happen to be. 235/2 is not an integer.
r(round(end/2)+1:end, round(end/2)+1:end) = 1; %perhaps

error in two _stage _sub
Q_phase = zeros (Nr,1) ;
ERROR IN main_SR
[AP1,DP1,p0] = two_stage_sub(H,K,bit,p);

You might have computed Nr using floating point arithmetic such as 0.35/0.001. If so... Don't Do That! Floating point computations are only approximate when decimal fractions are used.
