Cannot run the demo `software_dubins_demo.launch` in ` fastrack_crazyflie_demos` package

[hc825b]

Hi HJReachability team,

I'd like some help on running FasTrack.
I can launch software_demo.launch and see the simulation result in RViz,
but I cannot run software_dubins_demo.launch. The following error message will appear.

[ERROR] … MatlabFileReader: could not load file …/ros/src/fastrack/matlab/value_function.mat

I also tried to follow instructions in helperOC repository and generate value_function.mat using the MATLAB script ComputeTEB.m under …/ros/src/fastrack/matlab/, but the script will throw the following error.

Error using HJIPDE_solve (line 299)
Mismatch between plot and grid dimensions!

Error in ComputeTEB (line 143)
HJIPDE_solve(data0, tau, schemeData, minWith, HJIextraArgs);

Thanks for any help!

Our environment setup:
Ubuntu 16.04, ROS Kinetic and required ROS packages, and MATLAB R2016B
