Hi Hangcil, I have update your newest lib on today. Then I tried the ub & lb options.But when catkin_make, the terminal showing ```
"sci_arma::fmincon(std::function<double (arma::Col&)> const&, arma::Col&, arma::Mat&, arma::Mat&, arma::Mat&, arma::Mat&, arma::Col&, arma::Col&, options const&)'
collect2: error: ld returned 1 exit status"
Is there a Duplicate definition about the fmincon?
