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.

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.
