The input rotation matrix must be in the premultiply form for rotations. The default order for Euler angle rotations is "ZYX". example eul = rotm2eul(rotm,sequence) converts a rotation matrix to Euler angles. The Euler angles are specified in the axis rotation sequence, sequence. The ...

# Calculates rotation matrix to euler angles# The result is the same as MATLAB except the order# of the euler angles ( x and z are swapped ).def rotationMatrixToEulerAngles(R) : assert(isRotationMatrix(R)) sy = math.sqrt(R[0,0] * R[0,0] + R[1,0] * R[1,0]) singular = ...
My point is that there is no standard way to convert a rotation matrix to Euler angles. So, I decided to be (almost) consistent with the MATLAB implementation ofrotm2euler.m. The only difference is that they return the Euler angles with the rotation about z first and x last. My code ...
