How to display minimum valley point on the surface,which is drawn using symbolic variables

Hi

syms w0 w1;

J = .9486-1.0544*w0+.8916*w1+w0*w1+1.1*(w0^2+w1^2);

figure;ezsurf(J);

i plotted a 3D surface using above code.I would like to know how to display valley or minimum point (with 3 coordinates)

of that surface in the same plot.
