In MATLAB 7.0 (R14), the following command will clear the Command History:
com.mathworks.mlservices.MLCommandHistoryServices.removeAll;
In MATLAB 6.5 (R13), use the following command:
com.mathworks.ide.cmdline.CommandHistory.deleteAllHistoryForDesktop;
Please note that the use of these commands is not supported, and they may change in a future release.

This is really useful, since I often have to input a password to read an encrypted file. Is there a way to just delete only the previous line from the command history?
Looking at the methods of MLCommandHistoryServices, I see there are add, getAllHistory, getSessionHistory, and removeAll. It looks like I could get all history, remove all history, then iteratively add each element, shy of the last one to accomplish this, but I'm hoping there is a smarter option.

just type clc . It will clear your history window in matlab. If you want to clear the data as well, type: clc, clear

That's not useful if you're calling a function that takes a secret phrase for input, e.g. opening an encrypted file.
