3d plot by using points for generating hollow cylinder

Hi, I want to generate a hollow cylinder according to my 16 points where coordinate's points in x,y,z coordinate are: (r2 is outer radius r1 is inner radius L is length)

[0 0 r2];

[L 0 r2];

[0 -r2 0];

[L -r2 0];

[0 0 -r2];

[L 0 -r2];

[0 r2 0];

[L r2 0];

[0 0 r1];

[L 0 r1];

[0 -r1 0];

[L -r1 0];

[0 0 -r1];

[L 0 -r1];

[0 r1 0];

[L r1 0];

How can I do that? Thank you.

You can create patch objects for each component (outside, inside, and two ends). Try typing doc patch for info on patch objects. The drawCylinder function described here might help. Or this might help.
