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.

Community members learn about each other or track their own activities via community profile pages. To improve the user experience and address pain points, the community team has redesigned the entire page.

The biggest improvement is we replaced the cards and slider with a dashboard. In this Dashboard, you can easily track your activities by timeline and filter them by different applications (Answers, File Exchange, etc.). All of your stats, such as ranking and reputation, and badges earned are included in one dashboard. If you are looking at your own profile, there are tabs for managing followed content and communication preferences. We also introduced a content feed section, which brings together your contributions alongside your followed content

We encourage you to explore the new profile page. If you have any questions, comments, or suggestions, let us know by leaving a reply to this thread.

Happy New Year, everyone! We hope you enjoyed the Cody contest in 2020, learned new MATLAB skills, and made a friend or two. While the 2020 contest has concluded, the fun and learning never end.

Please take the 1-minute survey to talk about your experience (only 2 required questions). Our goal is to make future contests better and more appealing to you, so your feedback is critical to us.

Thank you in advance and hope to see you again in the 2021 contest.

We are excited to announce that Cody Contest 2020 starts today! Again, the rule is simple - solve any problem and rate its difficulty. If you have any question, please visit our FAQs page first. Want to know your ranking? Check out the contest leaderboard .

Happy problem-solving! We hope you are a winner.

Q5: I'm new to Cody. If I have some questions about using Cody, how can I get help?

A: You can ask your question by replying this post. Other community users might help you and we will also monitor the threads. You might also find answers here .

Q6: What do I do if I have a question about a specific problem?

A: If the problem description is unclear, the test suite is broken, or similar concerns arise, post your question(s) as a comment on the specific problem page. If you are having a hard time solving a problem, you can post a comment to your solution attempt (after submitting it). However, do not ask other people to solve problems for you.

Q7: If I find a bug or notice someone is cheating/spamming during the contest, how can I report it?

A: Use Web Site Feedback . Select "MATLAB Central" from the category list.

Q8: Why can't I rate a problem?

A: To rate a problem, you must solve that problem first and have at least 50 total points.

Today, I'm spotlighting Rik, our newest and the 31st MVP in MATLAB Answers. Two weeks ago, we just celebrated Ameer Hamza for reaching the MVP milestone. Today, we are thrilled that we have another new MVP!

Since his first answer in Feb 2017, Rik has been contributing high-quality answers every quarter!

Besides those high-quality answers, Rik so far has submitted 21 files to File Exchange, one of which was chosen by MathWorks as the 'Pick of the Week'. Check the shining badge below.

Congratulations Rik! Thank you for your hard work and outstanding contributions.
