Pop-up Command History for recalling, viewing, filtering, and searching
recently used commands in the Command Window
Pop-up Command History (2 min, 41 sec)
The Command History now displays in response to the up arrow (↑) in the Command
Window, by default. Previously, the Command History window occupied a designated
space on the MATLAB desktop. The following are additional features enhancing the
Command History.
Colored marks on the left side of the Command History indicate commands that
generate errors. These marks are of the same color as error messages in the
Command Window.
You can perform case-insensitive searches in the Command History, as well as search
for partial matches anywhere in a command.
You can select multiple commands using Shift + ↑ and rerun them at once. In
addition, brackets display on the left side of the Command History to indicate
commands processed as a group. Select the bracket to rerun the group.
You can filter commands to display only the results that match your search.
The Command History can display the command execution time.
For more information, see Command History.
Compatibility Considerations
To view the Command History window in a docked location as in previous releases of
MATLAB, click and then select Dock.
There is no longer any performance issue that justifies saving every nth command to
the command history file. Therefore, this option no longer appears in the Command
History Preferences. Instead, specify the total number of commands to save. The default
is 25,000 commands, but you can specify a value up to 1,000,000. For more information,
see Command History Preferences.
The history file is now named History.xml. Previously, it was named history.m. The
first time you access an existing history.m file, MATLAB automatically converts it to
History.xml, and you do not need to take further action.
