2019b installation problem
显示 更早的评论
I'm using 2019a Matlab version and have just tried installing 2019b together with the toolboxes. I see the following set of errors on the Matlab screen, when I try to launch it. The screenshot is attached.

I had this same problem with 2018b and now again with 2019b. Last year, Matlab Support solved it with the following solution:
=============================
Thank you for contacting MathWorks Support. The error you are receiving is usually caused by MATLAB having a pathing error. To resolve this error, please run the following commands in MATLAB in order:
restoredefaultpath
savepath
Once done, restart MATLAB and see if the error persists, if it does, please let me know so I can provide further troubleshooting.
=============================
Hope it works for you.

I had the same problem after upgrading from 2019a to 2019b and also with the 2020a prerelease.
This fixed it. Thanks!
