This manual page was written for the Debian GNU/Linux distribution because the original programs don't have a manual page. .PP .B mpbi is a version of .B mpb built with requiring inversion symmetry. It can only compute the eigenstates of structures with inversion symmetry, but runs twice as fast as .B mpb and requires half as much memory. .PP .B mpbi-split is equivalent to .B mpb-split but runs .B mpbi instances. .SH SEE ALSO .BR mpb (1), mpb-split (1). .SH AUTHOR mpbi was written by Steven G. Johnson . This manual page was written by Josselin Mouette , for the Debian GNU/Linux system (but may be used by others).
