| Apr 30, 2012 at 17:17 | comment | added | tmaric | Great, thank you so much! I've written out the minimization problem for the general quantity and I've seen that the matrix of the coefficients only comes from the geometrical configuration of the points, so I'll definitely store this and update it with respect to the change of point positions. Now all that is left is the code structure for the class templates, and here I'm at home. :) | |
