3D plotting in Matlab

How to plot a 3d 'U' shape in MATLAB parallel to XY plane?

[Dcember]

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

producing:

Thanks a lot ! This is what I was looking for. I just want to change its facing. How can I rotate it ?

My pleasure!

The easiest way is to use the rotate function. You will have to experiment with it to get the result you want.

You can also change its height above the (x,y) plane by substituting the ‘5’ multiplier to the ones call with the value you want.
