The revolution of a rotation matrix is often described with Euler angles, but can also be described in vector form using quaternions. Although there are many methods to perform a rotation, the most prevalent are based on directional cosine matrices and quaternions. ...

I've converted a quaternion to Euler angle using quat2eul(q,'ZYX') and a rotation matrix to Euler angle with function dcm2Angle(R,'ZYX'). However, the resulted graph is inverted (upside down). Example , if yaw angle from quaternion is up, yaw angle from dcm2Angle is down. ...
