Hi, i drew 4 cylinders, while removing a part from each and sticking them together. However, the cylinders are hollow and i want to at least have a bottom and top lid (same shape as the cylinders) if not fully fill it in 3D. Any help would be nice.

     h=figure(1);
set(h, 'WindowStyle', 'docked')
drawnow
for i=0:1.5:6
[x,y,z]= cylinder(1,1000);
z(:,386:617)=NaN;
x(:,386:617)=NaN;
y(:,386:617)=NaN;
h=surf(x+i,y,z, 'FaceColor', [0,0,1]);
hold on
