pub fn angular_distance<T: Float>(
angles1: &[T],
angles2: &[T],
) -> Result<T, IncompatiblePointsError>Expand description
Computes the distance between the points angles1 and angles2 on the unit n-sphere, where n
is the length of angles1 and angles2.
The last element of angles1 and angles2 is assumed to be in [0, 2pi] or [-pi, pi] (and the
other elements are in [0, pi]). An IncompatiblePointsError is returned when angles1 and
angles2 have different lengths.
