Open and Save Files

Create and open files, arrange document windows, and set preferences.

Check Syntax as You Type

Some entries appear in different colors in the Command Window and the Editor to help you identify MATLAB elements. This is known as syntax highlighting.

Check Code for Errors and Warnings

Use the MATLAB Code Analyzer to check your code for coding problems automatically.

Improve Code Readability

Use indentation, text-width indication, and code folding to make your code easier to read.

Find and Replace Text in Files

Find and replace text in the current file or multiple files. Automatically rename functions or variables.

Go To Location in File

Go to a specific location in a file, such as a line number or function definition, set bookmarks, navigate backward and forward within the file, and open a file or variable from within a file.

Display Two Parts of a File Simultaneously

You can simultaneously display two different parts of a file in the Editor by splitting the screen display. This feature makes it easy to compare different lines in a file or to copy and paste from one part of a file to another.

Add Reminders to Files

Annotating a file makes it easier to find areas of your code that you intend to improve, complete, or update later.
