In the past year, we've witnessed an exponential growth of ChatGPT and other Generative AI tools. AI has quickly become a transformative force across industries, from tech giants to small startups, and even community sites like ours. For instance, Stack Overflow announced its plan to leverage AI tools to draft a question or tag content; Quora built a ChatGPT bot to answer questions; and GitHub is piloting the AI tool for personalized content.
This trend in the community landscape makes me wonder what MATLAB Central community, especially in MATLAB Answers, can do to integrate AI and enhance the community.
Share with us your ideas in the comment session. Ideally one comment per idea, so that others can vote on a secific idea or have deeper discussions about it.
We launched the Discussions area with 6 channels, based on the existing types of content we see today in the MATLAB Central community.
I'm curious which channels you are most interested in participating, or which channels are missing.

MATLAB users come to Cody to learn MATLAB and the best way to learn is to learn from other community users. However, when you tried to see all solutions, you saw a message that you had to solve a new problem to unlock all the solutions or submit a solution of a smaller size. This is very confusing and we have been hearing this pain point from users.
Today, the Cody team is pleased to announce that players are able to see all solutions to a problem once they solve it correctly.
After solving a problem, you will see a button that says ‘View Community’s Solutions’, which will bring you to the list of all solutions.
Note that this is our first step in facilitating the learning aspect of Cody. We are actively working on improving the solutions list, so your input is valuable to us. Please let us know your comments or suggestions.
Every year, we show our appreciation to the top contributors by awarding two types of annual badges: Most Accepted badge and Top Downloads badge.
Most Accepted badge goes to the top 10 contributors whose answers received the most acceptances. Top downloads badge goes to the top 10 contributors with the most downloaded submissions.
In 2022, the recipients for Most Accepted are: @Walter Roberson, @Voss, @Star Strider, @Torsten, @Image Analyst, @Matt J, @KSSV, @Jan, @Stephen23, and @DGM.
The recipients for Top Downloaded are: @Cleve Moler, @Yarpiz, @John D'Errico, @Seyedali Mirjalili, @Rodney Tan, @Yair Altman, @Chad Greene, @Steve Miller, @Giampiero Campa, and @Scott Lowe
Congratulations and thank you again for your outstanding contribution in 2022!

Click the ‘Follow the contests’ button to follow/register for the contest. You will get notified when the contests start. After contests start, you will also receive important announcements and prize information.
In MATLAB Answers, oftentimes we see good comments that provide solutions in a question thread. Those comments should really be answers. On the other hand, there are some answers that do not offer solutions. Those answers should actually be comments. The answer/comment issue makes it harder for readers of a question thread to quickly identify useful information. To tackle this issue, the community team just released the MOVE feature!
What can be moved?
Answers and comments can now be moved in 4 ways within the same question thread:
  1. Change an answer to a comment
  2. Change an answer with comments to a group of comments
  3. Change a comment to an answer
  4. Move a comment
Who can move answers and comments?
New privileges have been awarded to contributors with 2000 reputation points or more. Privileged contributors will see move icons added in the list of actions available for answers and comments.
After an answer or comment is moved, an indication of the move will be displayed with the content.
As always, please let us know your thoughts by leaving a reply below.
When discussing Q&As in MATLAB Answers, we oftentimes need to reference a function in MATLAB Documentation. The process is quite tedious. You need to search the function in Documentation and copy & paste it into Answers. Now, you can simply use the ‘@doc:’ in Answers’ editor to easily reference a function in Documentation.
How does it work?
1) Simply type ‘@’ and you will see the option to add a Doc link. You can also directly type ‘@doc:’.
2) Start typing the function name. You will see a list of choices on the menu.
3)Select the function and a hyperlink to that function's doc page will be automatically inserted.
Give it a try and we hope you like it! Leave a comment if you have any questions or suggestions.

User Spotlight: Bruno Luong

Today, I'm spotlighting Bruno Luong, our newest MVP. Next, let's 'talk about Bruno'!
When we look at Bruno's stats chart below, we'll notice Bruno achieved this major milestone just in 3 years! This is amazing, right? Actually, we are still underestimating Bruno's contribution to the larger MATLAB/Simulink user community by just looking at his reputation points.
Before he started his active contribution to Answers in 2019, Bruno had been a top contributor to the newsgroup for MATLAB & Simulink products – comp.soft-sys-matlab. Sounds a bit old school? Leave a comment if you have participated or are still participating in the newsgroup. I remember back in 2016 when I first chatted with Bruno, he already had about 500 posts in the newsgroup!
Besides helping users with their questions, Bruno has also been contributing high-quality files to File Exchange. Check out the two prestigious badges below. They are showing the highest recognition from both the MathWorks team and millions of community users.
Congratulations, Bruno. We really appreciate your outstanding and long-time contributions to the MATLAB/Simulink user community!

Several major updates have been introduced to Answers’ reputation system! The updates include a new User Levels system, a new Editor indicator, and updated badges series.

1. User Levels

User Levels have become a best practice for many community sites to adopt. They help build trust in the community and provide recognition to contributors. There are 10 levels in the system and the labels will display next to users’ names throughout MATLAB Answers and on your community profile. We hope to see more users climb the ladder and level up!

2. Editor Indicators

Becoming an Editor (upon earning 3,000 points) is a huge milestone in Answers. Therefore, we introduced the Editor indicator to show our appreciation. From the screenshot below, you will notice a user can have both a User Level and an Editor indicator.

3. Updated Badge Series

Based on our analysis of existing badges, we decided to introduce 2 new badges into existing series and retire an entire badge series.

  • The Knowledgeable badge series and the Thankful badge series now have 5 levels.
  • The Revival badge series has been archived and is no longer being awarded. If you earned one of these badges, it would still show up in your community profile.

You will find more information on Answers help page . If you have any questions, comments or feedback, free feel to leave a comment below.
