Desktop Tools and Development Environment

Starting, Customizing, and Closing the Editor/Debugger

The MATLAB Editor/Debugger provides a graphical user interface for basic text editing features for any file type, as well as for M-file debugging. The Editor/Debugger is a single tool that you can use for editing, debugging, or both.

There are various ways to start the Editor/Debugger. The Editor/Debugger automatically starts when you open a document or create a new one, as detailed in these sections:

• Creating a New File in the Editor/Debugger
• Opening Existing Files in the Editor/Debugger
• Opening the Editor Without Starting MATLAB

After starting the Editor/Debugger, follow the instructions for

• Arranging Editor/Debugger Documents
• Preferences for the Editor/Debugger
• Creating and Editing Other Text File Types
• Closing the Editor/Debugger

This figure shows an example of the Editor/Debugger outside of the desktop opened to an existing M-file, and calls out some of the tool's useful features.
