ain/src/matlab/so3_demo_lower_band_limit.m">so3_demo_lower_band_limit</a>
  Demo to compute inverse and forward transform of complex
  function, using a non-zero lower harmonic band-limit - i.e. only
  harmonic coefficients with L greater than or equal to some L0
  are non-zero.

  Demo to compute inverse and forward transform of complex
  function, using only harmonic coefficients with even n.
