Hello, I am studying Robotics. But, I have some question about jacobian.
First of all, in this site, http://www.matlabinuse.com/Mastering_MATLAB/11080, said to me that if there is a rotation matrix[nx ox ax ; ny oy ay ; nz oz az ; 0 0 0 1], we use only ax, ay, az in order to solve jacobian about rotation. what is the reason?( I am sorry, the site is written in korean.)
