The code below makes a parameterized 3D surface. It looks like a circle intersected by a paraboloid of revolution. The figure looks fine, but I am getting warnings:
"Warning: Function behaves unexpectedly on array inputs. To improve performance, properly vectorize your function to return an output with the same size and shape as the input arguments....."
How can I improve the code to avoid the warnings?
Thanks in advance.
funx = @(r,th) r * cos(th) ;
funy = @(r,th) r * sin(th);
funz = @(r,th) 500-real(sqrt((4*125.*(r .* sin(th)+125))-(r .* cos(th)).^2));
parab3D=fsurf(funx,funy,funz,[0 500 0 2*pi],'MeshDensity',500,'EdgeColor','none') ;
