quaternion.m

18 Oct 2011 (Updated 18 May 2012)

quaternion class, vectorized, converts among rotation representations, numerical Euler propagation

File Information
Description	quaternion.m is a matlab class that implements quaternion mathematical operations, 3 dimensional rotations, transformations of rotations among several representations, and numerical propagation of Euler’s equations for rotational motion. All quaternion.m class methods except PropagateEulerEq are fully vectorized.
