Categorical navigation is now available in MATLAB Answers.

• Categories empower you to find, watch, and answer questions by topic and product, rather than product alone.
• Individual answers have been categorized using an AI model written by MathWorks developers. Read more about our method here.

FAQ

1. What if I've bookmarked or subscribed to a product?

The links will continue to work but use a different filter mechanism.  We encourage you to try the new category filter, to find more questions in your topic of interest.

2. Can I still select a product on the question?

Yes - and product and tags are factored into the text analytics algorithm.  Correcting those fields should improve the nightly categorization. 

Categories are also shown in the Help Center.

The community team is pleased to release a new design for File Exchange review section. The new design has addressed major pain points we heard from File Exchange users and improves the overall experience. Major improvements include:

1. Support editing ratings/comments

Editing is probably the most popular feature request from File Exchange users. Now, you are able to edit your ratings/comments. Simply click the ‘Edit’ link below your content.

2. Support replying to a comment

In the old design, the only way for the file author to reply to a comment is to create a new comment, which is very hard to track. With the new design, the authors can directly reply to a comment and their post has a blue background making it easier to see. Due to differences between the old and new commenting structures, replies to comments couldn't be reliably inferred, so all comments added prior to 7/14 are at the same indentation level. Replies will be indented from now on.

3. Support rich formatting and attachments

Using the new rich text editor, you are able to choose bold/italic text, insert code or image, create lists, or attach files.

4. Introduce the ‘Discussions’ tab

There is a new ‘Discussions’ tab where community users have conversations with the author or other community members for Q&As or general discussions. The discussions section supports threaded discussions to facilitate the conversations. We separate Discussions with Reviews so that different types of content are not mixed together.

This is a major change for File Exchange and we look forward to hearing from you. Simply reply to this article if you have any questions, comments, or suggestions.
