title: Matlab: animation
body: <p>I want to write a program which shows a visual animation of the orbit of satellite in 3D space, with the Earth's rotation.
  I can write a code which shows a visualisation of the orbit (simply comet3()). It is possible to rotate the 3D model of the Earth either.
  But I can't merge these two programs.
  I've seen some Youtube videos like "Satellite Orbit Analysis and Simulation (in MATLAB)". How has he done it? </p>
  
  <p>Is there any special stackexchange site for Matlab questions?</p>
