I would be greatful for any help!
Here is the code:
creates a three-dimensional surface plot:
[x,y] = meshgrid(1:0.5:10,1:20);
z = ((x^2)/(1+(x^2))) + y^2;

Use element-wise operations for exponentiation (.^) and division (./):
z = ((x.^2)./(1+(x.^2))) + y.^2;
Then, it works.
See Array vs. Matrix Operations for details.
