Hope it helps:
[y,z]=meshgrid(linspace(-10,10));
x=y.^4;
surf(x,y,z)
xlabel('x')
ylabel('y')
zlabel('z')

Thanks for replying. I want to display simple U shape in 3D(not meshgrid) which will be parallel to XY plane. How to do that? I tried to plot a parabola but it does not look like U.

Try this:
x = linspace(-pi*0.49, pi*0.49);
y = abs(tan(x));
z = 5*ones(size(x));
figure(1)
plot3(x, y, z, 'LineWidth',2)
grid on
