Matlab very slow using 100% CPU and RAM and still crashing

Hello im using matlab R2019b and having problems with the program running. after some minutes the program starts to freeze for some minutes then will unfreeze until the whole things repeats itself. It is unusable and will crash after inputting simple funtions like x=y. Im using a surface pro 6 with 8gb ram etc and other colleagues have the same hardware and it runs smoothly for them.

My first thought would be to scan for viruses. Also, use Resource Monitor and Task Manager to see if there is anything running in the background that are using most of your computer resources and that is interfering with your computer. Doing a cold reboot may solve the problem,a t least temporarily.

It is possible that the caches are too big and may have to be cleared.

Try the following to try and fix that issue if present.

>> restoredefaultpath

>> rehash toolboxcache

After this step, please use MATLAB / Simulink normally to see if the issue occurs again. If the issue is resolved, then you can save the new MATLAB search path by executing the following command:

>> savepath
