Editing Files Overview

MATLAB® Mobile™ allows you to create and edit MATLAB (.m) files, Live Editor (.mlx) files, and text (.txt) files.

While you are editing files, MATLAB Mobile saves your changes automatically, at regular intervals. You can also save changes by running a file (MATLAB files only) or by navigating to a different view. An unsaved file in MATLAB Mobile has an asterisk next to the file name; for example, test.m*.

To create or edit files, go to the Files view or use the edit command.

Editing Features

Basic MATLAB Editing

MATLAB Mobile provides the following editing functionality for writing and modifying MATLAB files:

  • Cut, copy, and paste

  • Undo and Redo

  • Syntax highlighting

  • Auto indentation

  • Parentheses matching


MATLAB Mobile autosaves the file to the Cloud while you are editing. If the device is not connected to the Cloud, the file is saved locally. When the device is connected again, the file is autosaved to the Cloud and the local file is deleted.

Keyboard Support

MATLAB Mobile supports the use of an external keyboard for editing.

Android Keyboard Shortcuts

Ctrl + RRun file
F5Run file
Ctrl + SSave file
Ctrl + CCopy selected text
Ctrl + VPaste selected text
Ctrl + XCut selected text
Ctrl + ZUndo
Ctrl + Shift + ZRedo
Ctrl + YRedo

These key combinations are supported when a an external hardware keyboard (for example, a Windows® Bluetooth® keyboard) is connected to the Android™ device.

File Editing Support

MATLAB Mobile supports the following functionality for file editing:

  • You can create, open, and edit MATLAB (.m) files, Live Editor (.mlx) files, and text (.txt) files only. Only MATLAB and Live Editor files can be run.

  • Using a phone, you can edit and run a Live Editor (.mlx) script, but you cannot create an .mlx file.

  • Images (.jpg and .png) can be viewed but not edited.

  • Other files are grayed out in the file browser and cannot be viewed nor edited.

  • You can have only one file open at a time.

  • Some very large files may take a long time to open, or may not open at all. These large files also can see performance degradation.

  • MATLAB Mobile autosaves a temporary local copy while you are editing.

File Size Limit

The file size limit for .m and .txt files is 300 KB.

The file size limit for .mlx files is 20 MB.


  • Android OS: You must have 6.0 or later to use the editor.
