clearcommanddeletehistoryMATLAB

I would like to clear the command history from the command line in MATLAB.

Best Answer

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.

MATLAB: Clear text typed with input() from the command history

After digging into the Java internals with the help of Yair's toolkit (see findJObj, uiinspect and checkClass), I found a relatively simple way to manipulate entries in the Command History:

% Get instance to the Command History
cmdhist = com.mathworks.mde.cmdhist.AltHistory.getInstance;
% Retrieve the Command History Table
chtable = findjobj(cmdhist,'property',{'name', 'CommandHistoryTable'});
% Select last row row
nrows = chtable.getRowCount
chtable.setRowSelectionInterval(nrows, nrows)
% Delete selected rows
chtable.deleteSelectedCommands
