• You can upload a maximum of 10 attachments in a 24-hour period. If you need to upload an additional file during this period, delete an existing attachment and upload the new file.

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.

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.

Accelerators

User Mentions

Available in: MATLAB Answers, MathWorks Communities, Community Highlights, Community Contests, Blogs

When you type @, a popup displays the community members already in the Q/A thread. As you keep typing, the list expands to include members not in the thread. A mentioned community member receives a notification when the question/answer/comment is posted. Each mention links the post to the community member's user profile.

Documentation Links

Available in: MATLAB Answers, MathWorks Communities, Community Highlights, Community Contests, Blogs

To add a link to a documentation page, type @ to insert "@doc:" (or type "@doc:" yourself) and then start typing the function name. In the resulting search popup, select one of the doc topics matching the text you typed to convert it into a hyperlink.
