# Welcome to mcu’s documentation!¶

A package for periodic wavefunction and crystallography analysis. mcu is designed to support large scale analysis and topological descriptions for periodic wavefunction.

## A quick look¶

A projected band structure can be plotted simply by:

 1 2 3 import mcu mymcu = mcu.VASP() mymcu.plot_pband() 

mcu faciliates the setup and plotting for 2D band structure. For example, one can visualize the Dirac cones of graphene:

 1 2 3 import mcu mymcu = mcu.VASP() mymcu.plot_band2D() 

or the spin texture:
