Hello guys, I am trying to fill the matrix (zeros) of values of vector into a circle shape.
A = zeros(50)
This is sketch of my intention, any idea how to fill point in circle?

If you have Image Processing Toolbox, one solution would be like this:
A = zeros(50);
A(25,25) = 1;
D = bwdist(A);
idx = D <= 24;
A(idx) = 1;
