Converts DCM into Euler angles (Varshalovich B convention). Syntax:
In the latter case, anglews is a row vector containing the three Euler angles, ordered as [alpha beta gamma].
Note: The problem of recovering Euler angles from a DCM is in general ill-posed. The function below is a product of very considerable amount of thought and has has passed rigorous testing. In all cases it either returns a correct answer or gives an informative error message.
