I've generated a cylinder as follows: [x,y,z]=cylinder([0,10,10,0],100);

z([1,2],:)=0;

z([3,4],:)=100;

mesh(x,y,z)

axis equal; I want to have the cylinder lying flat i.e. a rotation by 90d degrees. I've tried using the rotate function but couldn't get it to work, any suggestions?

I don’t understand what your problem with rotate is.

Try these:

[x,y,z]=cylinder([0,10,10,0],100);
z([1,2],:)=0;
z([3,4],:)=100;
figure(1)
hm = mesh(x,y,z);
rotate(hm, [1 0 0], 90)
axis equal
figure(2)
hm = mesh(x,y,z);
rotate(hm, [0 1 0], 90)
axis equal
figure(3)
hm = mesh(x,y,z);
rotate(hm, [1 1 0], 45)
axis equal
