hiphive_test.py: Code used to lunch hiPhive and phono3py for the lattice thermal conductivity calculation with the FC obtained from ML

hiPhive_convTest_PP.m: code used for the post processing of the hiPhive FC calculations. Here there are the scripts for plotting the matrix of FC and the difference between the DFT (from phonopy) and the ML (from hiphive) force constants.

compare_fcs.py: print the relative error between the hiphive FC and phonopy FC.
