I have the following portion:

N = size(p,1);
x = 1:N; y = x;
[X,Y] = meshgrid(x,y);
R = sqrt((2.*X-N-1).^2+(2.*Y-N-1).^2)/N;
Theta = atan2((N-1-2.*Y+2),(2.*X-N+1-2));
R = (R<=1).*R;
Rad = radialpoly(R,n,m);    
Product = p(x,y).*Rad.*exp(-1i*m*Theta);

I get the error in the following line:

Product = p(x,y).*Rad.*exp(-1i*m*Theta);

The error that I get is:

Index exceeds matrix dimensions.

I tried to "debug" the program, and found that the dimensions issue may be due to the following line:

[X,Y] = meshgrid(x,y);

The weird thing is that the program doesn't give me errors on most of the images I'm applying it on.

Do you know why I'm getting such error?

Thanks.

"p" is just a matrix passed to a function

Regarding the size, no, it is not of NXN size
