Help: Matlab takes forever with unrecognized commands, how can I fix this?

1 ビュー (過去 30 日間)
Lately I have been having a problem where if I mistype a command or variable in the command window, it will take forever to respond. For instance, I tried typing "igure" to open a new figure window and Matlab went into busy mode for 6 minutes(!) before it came back with:
Unrecognized function or variable 'igure'.
Did you mean:
>> figure
Six minutes. I don't ususally mistype commands (heavily relying on the tab key and the up arrow), but this is ridiculous. What's happening and how can I fix it?

It does appear to be a licensing issue. I have not solved it yet, but it is good to know where to look.

I found the answer in the link that Karim posted:
It was posted by Ryan Gray, and I quote:
Another possibility is that due to corporate configuration, the AppData folder gets stored on a network share, and MATLAB stores its preferences folder there by default. This can make it very slow to unusable. You will have to set the MATLAB_PREFDIR environment variable to point to a local folder. If your IT is very restrictive, you may only be able to locally write in C:\Users\%USERNAME%, so make a folder there. Just remember that the contents are particular to each MATLAB version. These day, it seems common to have the Documents folder on a network redirect as well, so you might have to consider changing your userpath to something local as well. I would also check that TMP and TEMP folders are local rather than on a network path.
This was indeed the issue. Specifically, I had to make an MATLAB_PREFDIR environment variable that pointed to a location on my C:\ drive.

I had this problem and found it was caused by some interaction with "MATLAB Drive" and "MATLAB Drive Connector". As soon as I stopped using the MATLAB Drive, the problem went away.

No problem, I am always amazed at how much I don't know about MATLAB when I use it almost every day.
