Hi!
I have a Matrix D=onse(N,N).
I would like to make a circle with radius R at the center at (i0,j0) with filled zeros.
I wrote something like that but it takes so long time in my sub-loop to calculate it. Do you have a better idea how can we make such "0" circle inside the matrix?
for i=1:N
for j=1:N
if ((i-i0)^2+(j-j0)^2)<(R^2)
D(i,j)=0;
end
end
end
Thank you for your help!
