Functions used to read pswf_t structs from WAVECAR files (VASP output). This code is based upon the Fortran program, WaveTrans, written by R. M. Feenstra and M. Widom from the Dept. of Physics at Carnegie Mellon University. To see the original work, please visit: https://www.andrew.cmu.edu/user/feenstra/wavetrans/

DEPRECATED, DO NOT USE: function to read a single band from a WAVECAR
pswf_t* read_wavefunctions | ( | char * | filename, |
double * | kpt_weights | ||
) |
Given char* filename pointing to a WAVECAR file (VASP output), constructs a pswf_t* containing the plane-wave coefficients and energies for each band at each kpoint for each spin.
