Yes, I had lookked at meshgrid a few times, but couldn't see how I could  
apply it when I don't have a function.

Sorry to continue to be dense on this, but does the above fit in with my  
code snippet?
Is your jj my j, and your ii my i? What is z in the above?
If I do...

y = zeros(n,num1);
spac2 = 12.0;
for i=1:n
        for j =1:num1
                x = j*spac1;
                y = i* spac2;
                z(i,j) = profile(2,j);
        end
end
surf(x,y,z)

I get...

error: surface: rows (Z) must be the same as length (Y) and columns (Z)  
must be the same as length (X)

So I am clearly misunderstanding your meaning.

Looked a few times, but can't see how it helps.
