Compute natural axis of rotation
ax = naturalAxis( computes the natural axis
of the provided rotation,
R. The natural axis is the axis of rotation
that corresponds to the natural angle of the rotation. See
naturalAngle for more
The returned natural axis,
ax, is a 3-by-1 unit vector. If the
natural angle is zero, the natural axis is the zero vector.
ax — Natural axis of rotation
Natural axis of the rotation, returned as a 3-by-1 unit vector.
