After 7 weeks of fun, the MATLAB Central community 20th anniversary contests have concluded! Together, we shared the art of MATLAB and contributed to the battle against the global pandemic. See the fantastic stats below.

• 1,700 entries created and 24,000 votes cast in MATLAB Mini Hack
• 6,300 tasks completed in Treasure Hunt

MATLAB Mini Hack Winners - Week 4

In Week 4, we invited the MATLAB Graphics team to help judge the entries. As the authors of the MATLAB functions used in every entry, they made sure every entry selected used a unique graphics function or technique from the other winners. Here are their choices:

1. Umbrellas by Shanshan Wang

Comment: Cool use of 'swarmchart' to make art from distributions; Only use of one of our newest graphics functions

2. Happy Sheep by Victoria

Comment: Cute!

3. Alien Giant by Jenny Bosten

Comment: Original idea, well textured, and efficient code

4. 3D Ultrasound by Adam Danz

Comment: Replicate source material very well. Effective use of lighting and material. Overall, impressive to produce this image given the limitation

5. Sunset in the Savanna by Sebastian Kraemer

Comment: Looks cool! Nice mix of 'image', 'fill' and 'scatter' commands.

6. Night Flight by Ratul Das

Comment: original; clever use of 'rectangle'

7. Lantern #2 by Tim

Comment: Nice use of 'getframe' to create a texture for 'surf' for a compelling picture

8. Geometric Design (6) by Daniel Pereira

Comment: Looks like some walls at MathWorks

9. Rosette 1313 by Alex P

Comment: Looks cool! Nice use of 'pcolor'

10. Mandelbrot contour by Sumihiro

Comment: Best use of contour!

11. Aim High by Murty PLN

Comment: Largest number of unique graphics objects for the Mini Hack (plot, patch,stairs,stem,text)

In the spirit of Mini Hack, the MATLAB Graphics team also created several cool graphs about the contest. Facing a similar space limit, I have picked only 2.

What’s new in Week 3?

In Week 3, we will add several new categories in which we hope to see more creative entries:

• Holidays
• Album covers
• Food & Drinks
• MathWorks logo
• Fractals

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.

Check out your favorite topic of interest and let us know how we're doing in the comments below!

In just one week, 500+ amazing entries were created. Math rocks and you rock!

Help us show the world the beauty of mathematics by sharing your work with your friends, classmates, or colleagues. You can also help fight the global pandemic by voting. For each vote, MathWorks will donate $1 to Direct Relief. See the Voting FAQs below for details.

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.
