clc & clear all?

In my command window clc & clear all are not working, previously I was working but now it seems no response?

[Ngonidzashe Nedziwe]

are there any commands or configuration edits u performed on you matlab software?

If this is indeed the case, this would be a pretty serious bug. How do you issue the command exactly and what is the literal effect? Does the problem persist after a reboot of your computer?

By the way, you shouldn't use clear all. Use functions to keep workspaces separated, or at the very least use clear variables.
