ALDAX = [real]
Default: ALDAX = 1.0-AEXX
Description: ALDAX is a parameter that multiplies the LDA exchange functional or the LDA part of the GGA exchange functional.
ALDAX can be used as the fraction of LDA exchange in a Hartree-Fock/LDA or Hartree-Fock/GGA hybrid functional.
Note that for versions of VASP prior to 6.4.0, ALDAX was constrained to be equal to 1.0-AEXX. This constraint is lifted since VASP.6.4.0.
