void g2o::RobustKernelCauchy::robustify ( double  squaredError, Eigen::Vector3d &  rho  ) const

virtual

compute the scaling factor for a error: The error is e^T Omega e The output rho is rho[0]: The actual scaled error value rho[1]: First derivative of the scaling function rho[2]: Second derivative of the scaling function
