Syntax

R = Frames.axesRotations(sequence, angles, der_angles);

Description

This function returns orientation object R that describes the orientation defined by three elementary rotations in a given sequence, each rotated by angles. The angular velocity vector R.w is calculated from the angle derivatives der_angles.
