 Dear all,
 Do you have any idea about the exact meanning of incremental Fock  matrix which
 is default setting for direct SCF.
 What's the non incremental fock matrix?
 here I put the Gaussian's manual which I don't understand:
 "IncFock:
 Forces use of incremental Fock matrix formation. This is the default for direct
 SCF. NoIncFock prevents the use of incremental Fock matrix formation, and it is
 the default for conventional SCF. "
