Error using ones Size inputs must be integers?
显示 更早的评论
hello every one i have a problem with my code for error
r =[zeros(size(img2,1),size(img2,2)) ones(size(img2,1),size(img2,2)/2)];
where img2 an image of size (111 235)
Error using ones
Size inputs must be integers
and i want to have an image of the same size of img2

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

r(:, round(end/2)+1:end) = 1; %perhaps

Works for me.
What shows up for
which round

suggests that you might be running into bugs with old versions of MATLAB, in the R2011 time frame. Which MATLAB version are you using?

hi everyone in my code i have an error please help me out
Error using zeros
size inputs must be integers.
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.
