# mpbi(1)

mpb with inversion symmetry mpbi-split - mpb-split with inversion symmetry

## NAME

mpbi - mpb with inversion symmetry\
 mpbi-split - mpb-split with inversion symmetry

## DESCRIPTION

This manual page documents briefly the **mpbi** and **mpbi-split** commands. This manual page was written for the Debian GNU/Linux distribution because the original programs don't have a manual page.

**mpbi** is a version of **mpb** built with requiring inversion symmetry. It can only compute the eigenstates of structures with inversion symmetry, but runs twice as fast as **mpb** and requires half as much memory.

**mpbi-split** is equivalent to **mpb-split** but runs **mpbi** instances.

## SEE ALSO

[**mpb**(1)](/mpb/1.md),[**mpb-split**(1)](/mpb-split/1.md).
