wulfric.cell.get_params

wulfric.cell.get_params(cell)

Computes lattice parameters of the cell.

Parameters:

cell(3, 3) array-like

Matrix of a cell, rows are interpreted as vectors.

Returns:

afloat

Length of the \(\boldsymbol{a_1}\) vector.

bfloat

Length of the \(\boldsymbol{a_2}\) vector.

cfloat

Length of the \(\boldsymbol{a_3}\) vector.

alphafloat

Angle between vectors \(\boldsymbol{a_2}\) and \(\boldsymbol{a_3}\) in degrees.

betafloat

Angle between vectors \(\boldsymbol{a_1}\) and \(\boldsymbol{a_3}\) in degrees.

gammafloat

Angle between vectors \(\boldsymbol{a_1}\) and \(\boldsymbol{a_2}\) in degrees.
