Plotting path on torus

Hy everyone!

I'm quite new at Matlab and so I try to get a little bit familiar with plots.

Due to this I already managed to create a 3D surface plot of a torus and an plot3 - Plot of a helix.

Now my next goal is to produce a plot where I visualize some kind of path on my torus (I'm not sure, whether "geodesic on a torus" is the correct name), which finally should look a little bit like a toroidal coil with a copper winding on it.

This is my parametrization for the torus:

x = ( (a+b)/2 + (b-a)/2 .*cos(theta) ) .*cos(phi)

y = ( (a+b)/2 + (b-a)/2 .*cos(theta) ) .*sin(phi)

z = (b-a)/2 .* sin(theta)

Unfortunatelly my tries failed, so I would be glad if some on you can help me!

Thanks in advance!
