I tried creating cylinder using patch fucntion but the top and bottom faces are open.
Below is my code-
%% Cylinder
[l,m,n]=cylinder;
fvc=surf2patch(l,m,n);
figure()
o=patch(fvc,'FaceColor','r');
o.FaceAlpha=0.2;

Try this —
%% Cylinder
[l,m,n]=cylinder;
figure()
surf(l,m,n)
hold on
patch(l(1,:),m(1,:),n(1,:),'r')
patch(l(2,:),m(2,:),n(2,:),'g')
hold off
title('Top End')
figure()
surf(l,m,n)
hold on
patch(l(1,:),m(1,:),n(1,:),'r')
patch(l(2,:),m(2,:),n(2,:),'g')
hold off
view(30,-30)
title('Bottom End')
The cylinder results are simply matrices of two vectors defining the top and bottom of the cylinder (unless a particular shape is supplied for the radius argument, then there are more rows to the cylinder output and only the first and last rows define the ends). To put ‘caps’ on either end, create separate patch objects for each end vector, and supply whatever colours are desired.
