09 May 2011 FiledCircle This function create a matrix with a filled circle. Author: Silvano Bertoldo Simon, Jan

Instead of two slow loops the complete computation can be vectorized:
x = 1:2*nRadius;
y = transpose(x);
mMatCircle = bsxfun(@plus, (x - vCenter(1))^2, (y - vCenter(2))^2) < (radius^2);
The function is well documented, but the style differs from the standard of Matlab's toolbox functions such that "help FilledCircle" is not really helpful. Although I love Italian, English comments would be better.
