biotite.structure.unitcell_from_vectors

biotite.structure.unitcell_from_vectors(box)[source]

Get the unit cell lengths and angles from box vectors.

This is the reverse operation of vectors_from_unitcell().

Parameters
boxndarray, shape=(3,3)

The box vectors

Returns
len_a, len_b, len_cfloat

The lengths of the three box/unit cell vectors a, b and c.

alpha, beta, gammafloat

The angles between the box vectors in radians.
