traj_gen:/usr/include/eigen3/Eigen/src/Core/DenseCoeffsBase.h:425:

[Ackermann10]

Hi, When I run the code,I met this error: traj_gen: /usr/include/eigen3/Eigen/src/Core/DenseCoeffsBase.h:425: Eigen::DenseCoeffsBase<Derived, 1>::Scalar& Eigen::DenseCoeffsBase<Derived, 1>::operator()(Eigen::Index) [with Derived = Eigen::Matrix<float, -1, 1>; Eigen::DenseCoeffsBase<Derived, 1>::Scalar = float; Eigen::Index = long int]: Assertion `index >= 0 && index < size()' failed. How to solve this problem? best regards
