surfs and meshplot problem

Hi I want to plot a function of two variables with surfc, I get the error Z must be a matrix not a scalor or vector.

My function is like this: %

 Z=exp(M.*log(eps)+v.*eps), M=[1:30] eps=[11:40]

I want to plot surfc(Z,M,eps). could you help me?

 plot3(Z,M,eps)

Answer 2

[M,EPS] = meshgrid(1:30,11:40);
v = 3;
Z = exp(M.*log(EPS)+v.*EPS); 
surfc(M,EPS,Z)
set(gcf,'render','zbuf')
