skspatial.objects.Vector.different_direction

Vector.different_direction(**kwargs: float) → Vector

Return a simple vector that is in a different direction.

This is useful for finding a vector perpendicular to the original, by taking the cross product of the original with the one in a different direction.

Parameters

kwargsdict, optional

Additional keywords passed to Vector.is_zero() and Vector.is_parallel(). Vector.is_zero() is used to ensure the input vector is not the zero vector, and Vector.is_parallel() is used to ensure the new vector is not parallel to the input.

Returns

Vector

A unit vector in a different direction from the original.

Raises

ValueError

If the vector is the zero vector.

Examples

>>> from skspatial.objects import Vector

>>> Vector([1]).different_direction()
Vector([-1])
>>> Vector([100]).different_direction()
Vector([-1])
>>> Vector([-100]).different_direction()
Vector([1])
>>> Vector([1, 0]).different_direction()
Vector([0., 1.])
>>> Vector([1, 1]).different_direction()
Vector([1., 0.])
>>> Vector([1, 1, 1, 1]).different_direction()
Vector([1., 0., 0., 0.])
