dim=64;
[kx,ky]=meshgrid(-1:2/(dim-1):1);
circ=sqrt(kx.^2+ky.^2)<1;
kx=kx/2;
ky=ky/2;
alp=asin(0.8);
k0=1/sin(alp);
k=256;
kz=sqrt(k0^2-(kx.^2+ky.^2));
Gx=sqrt(k0./kz).*((k0*ky.^2+kz.*kx.^2)./(k0*(kx.^2+ky.^2)));
Gy=sqrt(k0./kz).*((kz-k0).*kx.*ky)./(k0*(kx.^2+ky.^2));
Gz=sqrt(k0./kz).*(kx./k0);
z=-64:1:63;
[r,c]=size(z);
mz=pi*64/(256);
Ex=zeros([k,k,c]);
Ey=zeros([k,k,c]);
Ez=zeros([k,k,c]);
for jj=1:c
Ex(:,:,jj)=fftshift(fft2(exp(1i*kz*z(jj)*mz).*Gx.*circ,k,k));
Ey(:,:,jj)=fftshift(fft2(exp(1i*kz*z(jj)*mz).*Gy.*circ,k,k));
Ez(:,:,jj)=fftshift(fft2(exp(1i*kz*z(jj)*mz).*Gz.*circ,k,k));
end
I =Ex.*conj(Ex)+Ey.*conj(Ey)+Ez.*conj(Ez);
M=I(k/2,:,:);
M1=squeeze(M).';

I have problem to perform for loop operation, I used above method to perform
for loop operation. Can anyone help me to perform this for loop operation in
other method it will be great helpfor me
thanking you in advance for your kind help

Your script runs here (R2012a, 64bit, Windows7) and produces an image. I cannot see any problem.
Do you get a warning or error message? You need to be more specific.
