Why is R2020a slow to return errors?
11 次查看（过去 30 天）
When I switched to R2020a (Windows), I noticed that a simple error at the command line takes about 20 seconds to resolve,
% Simple mistyping of command "min" cause Matlab to hang for 20 seconds
Unrecognized function or variable 'muin'.
% Nonsense command causes similar hang time
Unrecognized function or variable 'asdfasdfkkasdfasdf'.
Any suggestions of how to eliminate this? I am curious which internal process is hanging.

Do you have any network directories on your MATLAB path? If MATLAB has to search those network directories to determine if there's a potential match to suggest as a correction (the "Did you mean" functionality) that could slow the error process down.
Try temporarily removing those directories from the MATLAB path and check if the problem is resolved.
