[SciPy-Dev] suggestion re. scipy.spatial.transform.Rotation

[Phillip Feldman]

I've noticed that this class supports four of the five common
representations of a rotation.  The one that's missing is the rotation
matrix.  I can supply code that converts an arbitrary sequence of Euler
rotations into a rotation matrix.  It would also be nice to be able to go
in the reverse direction, but I haven't yet figured that out.

*class *scipy.spatial.transform.Rotation(*quat*, *normalized=False*,
*copy=True*)[source]

Rotation in 3 dimensions.

This class provides an interface to initialize from and represent rotations
with:

   -

   Quaternions
   -

   Direction Cosine Matrices
   -

   Rotation Vectors
   -

   Euler angles
