tenpy.algorithms.dmrg.full_diag_effH(effH, theta_guess, keep_sector=True)

Perform an exact diagonalization of effH.

This function offers an alternative to lanczos().

Parameters:

• effH (EffectiveH) – The effective Hamiltonian.

• theta_guess (Array) – Current guess to select the charge sector. Labels as specified by effH.acts_on.
