wulfric.Cell.scalar_products

wulfric.Cell.scalar_products(cell)

Returns pairwise scalar products of the lattice vectors:

• \(\boldsymbol{a}_2\cdot\boldsymbol{a}_3\)

• \(\boldsymbol{a}_1\cdot\boldsymbol{a}_3\)

• \(\boldsymbol{a}_1\cdot\boldsymbol{a}_2\)

Parameters:

cell(3, 3) array-like

Cell matrix, rows are interpreted as vectors.

Returns:

sp_23float

Scalar product of the vectors \(\boldsymbol{a}_2\) and \(\boldsymbol{a}_3\).

sp_13float

Scalar product of the vectors \(\boldsymbol{a}_1\) and \(\boldsymbol{a}_3\).

sp_12float

Scalar product of the vectors \(\boldsymbol{a}_1\) and \(\boldsymbol{a}_2\).
