4.3.24. ham.dat

(For the FullDiag method) When OutputHam=1 in the CalcMod file, the Hamiltonian calculated by \({\mathcal H}\Phi\) is outputted by the MatrixMarket format. The recalculation by using this file can be down when InputHam=1 in the CalcMod file. An example of the file format is as follows.
