Run feature

Available in: MATLAB Answers

The Run feature allows you to write, run, generate output and validate code inside the editor window without having to start up MATLAB. Run evaluates code using the most recent MATLAB release only.

Some notes about Run:

  • To use Run, your text must be formatted as code using the options on the Code menu.
  • Run is not available on mobile devices.
  • Run does not support MATLAB Coder and GPU Coder toolboxes.

Run feature example

Attachments with Run feature

Attached files are automatically included when you run your code in MATLAB Answers.

This example Answer has an attachment file named mathworks-icon.png, and it is available in the current directory of MATLAB for the code to use. The code reads the image from the attached file and then displays the image.

Code Examples with Run feature

Available in: MATLAB Answers

A code example is sample code that appears as indented monospaced text with MATLAB syntax highlighting. You can use a code example when you don't want the code to be executed by Run.
