Assigning colors on a cylinder

Hi,

Assume a cylindrical surface is divided into horizontal and vertical (equal) segments. I need to assign colors to each square area according to some known values (e.g. each color represents a real number vary between 0.1 and 3)

Any suggestion would be appreciated.

What exactly is your question? How to draw that thing? something else?

Yes. Drawing a 3D cylinder with colors represent real values.

Simplest way

[x,y,z] = cylinder;

surface(x,y,z, 'FaceColor','texturemap',...
'EdgeColor','none','Cdata', rand(10))

Gives random coloring to the cylinder. Another approach would be to supply a texture to the cylinder and wrap it with it.

Did you look in the help at the cylinder() function? It shows lots of cylinders with color sides.
