Why do I see the error "Caught unexpected fl::except::IInternalException" when using the "plot" function?
显示 更早的评论
When I have a plot function in my code it does not plot. Instead it gives this error:
ERROR : Caught unexpected fl::except::IInternalException
What does this mean and how is it fixed?

This error might appear if you have another function named "plot" on your path. Execute the following line to identify all functions named "plot" on your path.
>> which -all plot
If there is a user-defined function listed above the built-in, it may need to be renamed or removed from your path.
Note that you may see a number of other plot functions that are located in the MATLAB install directory. This is expected. They implement specific functionality for other built-in classes.

There was a run of people for which it was due to namespace issues/ The driver version of it only seems to have cropped up with some ubuntu.

Well, for me, it happened due to the graphics driver issue. The OS is ubuntu 16.04 LTS. To solve this problem, type:
opengl info
There, Matlab will give you low-level graphics troubleshooting methods.
The method of starting Matlab with software OpenGL solved my problem:
rik@ideapad:~$ matlab -softwareopengl
