Minimum acceleration trajectory does not work

[LTH14]

Hi, I am trying to run your code on trajectory optimization and find that if I change the traj_opt7 function used in trajectory_generator.m to traj_opt3 or traj_opt3c, it does not work anymore (BTW there is no traj_opt5.m in the repo). When I use traj_opt3, the trajectory goes to very far away from the desired trajectory. When I use traj_opt3c, the quadrator cannot start moving. Any idea on how to solve this? Thanks a lot!
