Set the range of values of x and y of interest, then use meshgrid and surf
doc meshgrid
doc surf

Accepting an answer shows, that the problem is solved. Is it solved already?

Perhaps an example will suffice.
% plot 2-x^2+y^2 for x=[-1,1], y=[-1,1]
x=linspace(-1,1,10);
y=linspace(-1,1,10);
[X Y]=meshgrid(x,y);
Z=2 - X.^2 + Y.^2;
surf(X,Y,Z)

x = linspace(-10, 10, 100);
y = linspace(0, 10, 100).';
f = x .^ 2 ./ y;
surf(x, y, f)
