How to superimpose one surface onto another?

Hello,

I have a basic 'shape' or 'surface' based on a simple formula (i.e., z = x + y).

I have another basic 'shape' or 'surface' based on another simple formula (i.e., z = 2x + y).

I would like a way to superimpose these two 'shapes', 'surfaces', or 'formulae' on top of each other so that they appear in the same 'plot' or 'box'.

How can I accomplish this? I can provide clearer instructions if this is not clear.

Thank you.

Z=randn(11,11);
Z1=randn(11,11)+2;
X=[1:11];
Y=[1:11];
surf(X,Y,Z)
hold on
surf(X,Y,Z1)
hold off

Two surfaces plotted on the same plot
