MATLAB problems after starting

Hello!

I'm using the matlab from my company, and the license is successfully installed. But after start I will always get the errors in the picture, which means all basic functions can not be used. I asked the IT support and they can not solve it either and let me to search the support from your side. Could you please have a look how to solve it?

Best regards,

Xiaochen Gao

These do not look good:

Unrecognised function or variable 'fullfile'

Unrecognised function or variable 'pwd'

Unrecognised function or variable 'docroot'

Did you try reinstalling?
