Hello,
I'm using Matlab R2018a on a ubuntu 18.04 server and when trying to use tabularTextDatastore i got the next error:
identifier: 'MATLAB:err_while_looking_up_function'
message: 'An error occurred while trying to determine whether "readData" is a function name.'
name: 'tabularTextDatastore'
line: 120
cause:
identifier: 'MATLAB:dispatcher:loadLibrary'
message: 'Can't reload '/usr/local/MATLAB/R2018a/bin/glnxa64/libmwsl_graphical_classes.so''
I checked /usr/local/MATLAB/R2018a/bin/glnxa64/ and the file is there....

We see this error as well. We already tried to reinstall Matlab and Ubuntu several times. We found that the issue does not occure when we only install Matlab and Matlab Coder without any Toolboxes. If Toolboxes, like Machine Learning Toolbox, are additionally installed the error is back.

We talked to the Tech support on this. They suggested to install openjdk-8-jre as it depends on the same packages.
Use
sudo apt-get install openjdk-8-jre

I solved it by creating a directory named "exclude" within "/usr/local/MATLAB/R2018a/bin/glnxa64/" and puting "libmwsl_graphical_classes.so" in it
