How do I extract surface plot data from a figure?

Hello,

I would like to find out hot to obtain surface plot data from a figure. I plotted data using,

surf(X,Y,Z);

I then saved the file as a figure.

Subssequently, I would like to find out how I can extract the X,Y,Z from the figure (not through the surf object)

Thanks.

x=1:5;
y=1:5;
z=randn(5,5);
fprintf('z was : \n');
disp(z);
figure;surf(x,y,z);

clear all

ch=get(gca,'ch');
x=get(ch,'xd');
y=get(ch,'yd');
z=get(ch,'zd');

fprintf('z is now;\n');
disp(z);
