Hi Lukas, Thanks for the prompt answer. I see the quaternion_oo is not released yet, right? How is the overlap with the quaternion package? The latter seems to be gradually abandoned... Last release is from 3 years ago. I will check what is missing in quaternion_oo that the robotic toolbox requires. I will also benchmark different versions of the same algorithm. Is that OK with you? With the functions that are already implemented in quaternion_oo, shall I create aliases to avoid changing the Robotic toolbox? Shall I put this aliases in the Robotic toolbox? What do you suggest? -- JuanPi Carbajal ----- "Complex problems have simple, easy-to-understand wrong answers."
