I want to make it very succinct, but it doesn't seem to work

[x,y] = meshgrid(linspace(-10,10,100));
z = sqrt(1+0.2*x.^2+0.2*y.^2);
Then you can plot it in many ways. Examples
figure(1)
contourf(x,y,z)
colormap(jet)
colorbar
axis equal
figure(2)
surf(x,y,z)
colormap(jet)
colorbar
figure(3)
surf(x,y,z,'EdgeColor','none'), hold on
surf(x,y,-z,'EdgeColor','none')
colormap(jet)
colorbar
axis equal
