Does anyone know how to make a cylinder without using the cylinder function? Like, will meshgrid be a good way to start? I would really appreciate some advice!
Thanks a lot!

It all depends on what you want as an end result. Do you want a mesh of the cylinder shell, do you want a label map for a filled cylinder, or do you want a label map for the cylinder shell only?

Depending upon what you want as a result, this can be straightforward.
Example —
a = linspace(0, 2*pi);
crcl = [cos(a); sin(a)];
figure
surf([crcl(1,:); crcl(1,:)], [crcl(2,:); crcl(2,:)], [2*ones(size(a)); ones(size(a))])
axis equal
This creates a cylinder with a radius of 1 and a length of 5.

Hi, how can I control the radii and the height, and also the height devision?
Basically I need to create a parametric code where the user inputs the radius and length of the cylinder, number of theta division, number of z divisions and Matlab generates a meshgrid of the surface of the cylinder, based upon the points.
Thanks.

hello and if I wanted that same figure, but in the form of vectors to solve equations on that domain?
