Intrinsic angles corresponding to a given rotation matrix R and a rotation sequence SEQ by our new function
rotm2ang
The function partially extends the function
rotm2eul
from Robotics System Toolbox in the version <=2021a.
The function rotm2ang suports all 6 permutations: XYZ, XZY, YXZ, YZX, ZXY, ZYX.
The function rotm2eul supports ZYX, ZYZ, XYZ in the version <=2021b and all permutations above in later versions.
The code
demo1.m
compares outputs of rotm2ang and rotm2eul .
The code
demo2
provides additional visualization
An explanation how the function rotm2ang works is explained in the article of Radek Lehner, Jan Valdman, Helena Zidkova (in preparation).
