AMGGAX = [real]

| = 1.0 | if LHFCALC=.FALSE. |
Description: AMGGAX is a parameter that multiplies the meta-GGA exchange functional (available as of VASP.6.4.0).
AMGGAX can be used as the fraction of meta-GGA exchange in a Hartree-Fock/DFT hybrid functional (possible since VASP.6.4.0).
| Important: AMGGAX can be used only if LHFCALC=.TRUE. |
