How can I combine two existing figures in one?

Hello all, I have two figures with a surface plotted in each one.The figures have the same axes, titles,.... How can I have these two together in one figure?

Do you mean you want to make 'subplot' figure ?, or want to plot two surfaces in a same axes ?

Akira Agata, Thank you for your comment! Basically, this is what I have:

figure

f=fit( [x, y], z, 'poly23' );

plot(f, [x, y], z);xlabel('x');ylabel('y');zlabel('response');

figure

f=fit( [x, y], z, 'poly23' );

plot(f, [x, y],z,'style','contour'); xlabel('x');ylabel('y');zlabel('response');

now I want to have these two in a same axes.(and I'd like to mention that I was not able to use fsurf function ) Thanks.

Nilou-san,

Thanks for giving me the detail. OK, the following is sample code for plotting your two plots in the same axes. I hope this will be helpful for you!

rng('default'); % for reproducibility
x = sort(rand(10,1));
y = sort(rand(10,1));
z = sort(rand(10,1));

f1 = fit( [x, y], z, 'poly23' );
f2 = fit( [x, y], z, 'poly23' );

figure
plot(f1, [x, y], z);
hold on;
plot(f2, [x, y],z,'style','contour');
xlabel('x');
ylabel('y');
zlabel('response');

 Akira Agata Thank you very much. it is perfect. 
just another question, how can I shift the second plot vertically? I need two plots in the same axes and also with different vertical position.
Thanks again.
