How to plot a 3d cylinder ?

hey there, I'm tring to plot a 3D cylinder, i wrote this code (and it doesnt work):

R=1;
z= linspace(0,2,.1);
phi= linspace(0,2*pi,pi/10);
[n,m] =meshgrid(z,phi);
x1=R.*cos(m);
y1=R.*sin(m);
z1=n;
surf(x1,y1,z1);
axis equal

thanks a lot !

Did you look at the cylinder() function, and the examples in the help? Is there some reason why you don't use that?
