is_orthogonal

biotite.structure.is_orthogonal(box)

Check, whether a box or multiple boxes is/are orthogonal.

A box is orthogonal when the dot product of all box vectors with each other is 0.

Parameters:

boxndarray, dtype=float, shape=(3,3) or shape=(m,3,3)

A single box or multiple boxes.

Returns:

is_orthgonalbool or ndarray, shape=(m,), dtype=bool

True, if the box vectors are orthogonal, false otherwise.

Notes

Due to possible numerical errors, this function also evaluates two vectors as orthogonal, when their dot product is not exactly zero, but it is within a small tolerance (\(10^{-6}\)).
