Saving M-Files

After making changes to an M-file, you will see an asterisk (*) next to the file name in the title bar of the Editor/Debugger. This indicates there are unsaved changes to the file.

To save the changes, use one of the Save commands in the File menu:

• Save - Saves the file to its existing name. If the file was newly created, the Save file as dialog box opens, where you assign a name to the file and save it. Another way to save is by using the save button on the toolbar.
• Save As - The Save file as dialog box opens, where you assign a name to the file and save it. You do not need to type the .m extension because MATLAB automatically assigns the .m extension to the filename. If you do not want an extension, type a . (period) after the filename.
• Save All - Saves all named files to their existing filenames. For all newly created files, the Save file as dialog box opens, where you assign a name to each file and save it.

You can also save and run a file - for instructions, see Running an M-File.

Accessing Your Source Control System

If you use a source control system for M-files, you can access it from within the Editor/Debugger to check in files. See Chapter 9, Interfacing with Source Control Systems.
