在 MATLAB Online 中打开

I have installed MATLAB R2018b on Ubuntu 18.04.1 LTS. When I open MATLAB in terminal, the following message shows up:

MATLAB is selecting SOFTWARE OPENGL rendering.

And when I close MATLAB, I get the following error in terminal:

Exception in thread "Thread-8": java.lang.NullPointerException

  at java.lang.Thread.run(Thread.java:748)

.Also, Help Browser doesn't work properly. It doesn't show figures, and when I search "parallel computing", MATLAB shows the following error in command window:
