Syntax

Q = Quaternions.planarRotation(e, angle);

Description

This function returns quaternions orientation Q that describes the orientation to rotate in the plane along unit axis e from frame 1 into frame 2 with angle angle. Note, "e" must be a unit vector. However, this is not checked in this function and the function will return a wrong result, if length(e) is not one.
