Hi, is there anybody who knows how to calculate the approximation of harmonic map by solving the sparse linear least square problem to minimize the energy E_harm?
I’m following the article “Multiresolution Analysis of arbitrary meshes” by Eck et al. but can’t figure out what to do in detail.
Also, what must i do to calculate the inverse map?
PLEASE HELP! 
you lost me after “Hi, is there anybody who knows how to…”
