We ordered too many T-shirts! Want one?

Want a MATLAB T-shirt? We have 10 more to give out in the 10 days between now and Oct. 30th. You might win a MATLAB T-shirt by doing any of these activities:
  • Vote on entries you like from the Mini Hack contest
  • Solve Cody problems in the Cody 10th contest
  • Create or remix entries in the Mini Hack contest
The more activities you do, the higher your chance to win. Every day, we will pick a winner.
We had another wonderful week of community contests 2022. In week 2, the voting for Mini Hack started! About 1000 votes have been cast on 300+ entries. In Cody 10th Anniversary contest, we already have 85 finishers for the two special groups: Matrices and Arrays and Plotting and Visualization.
Now, it’s time to announce the weekly winners!
MATLAB Mini Hack Winners - Week 2
Amazing entries keep coming in every day. In week 2, we announced a space category to celebrate the milestone of NASA’s Dart mission. We’ve picked 4 winners for this new category.
Winners of other categories are:
Congratulations! Each of you won a MathWorks T-shirt. If this is the second time you won, you have the option to choose a MathWorks hat or a coffee mug!
Cody 10th Anniversary Winners - Week 2
  • The top 3 players for solving most problems in week 2 are Mohammed, Armando Longobardi, and Stefan Abendroth, Congratulations! Each of you won an Amazon gift card.

Good luck! We hope you are the winner.
This is not a question, but a point of discussion for the entire community. I am aware that every 1/2 months this theme comes out, but until this is not fixed it is totally necessary that this comes, indeed, out. And I said "fix" because Mathworks has to understand that a dark theme is not only a visual/aesthetic matter, it is a substantial part of the game. Most of the OS, GUIs, programs are actually in dark mode, and a vast majority of the users makes indeed use of a global dark mode. How much one does like it is personal, but the benefits to power savings and eye health is instead a fact. Mathworks being ignoring this for years is nothing but ridiculous. Of course it is not an easy task, but every minute of committment for it is worthy. And nope, Schemer is not helpful because it does not provide a real fix to this question.
I feel free to suggest something similar to the Spyder's dark theme, which came out like 2 years ago if I remember correctly.
Of course, my point is not being disrespectful (I am instead very respectful to the huge efforts of Mathworks for making this wonderful program run). But, form a user's point of view, the fact that not a single word has so far come out from Mathworks about a dark theme (meaning that for sure we will not see it in a timing of months) requires us to put a strong pressure on this.
Mathworks, please: it's time for a dark theme.

In the past 2 months, we had a lot of fun together playing in the two contests. To make future contests better and more appealing to you, we created a 1-minute survey to understand your experience.

Your feedback is critical to us. Thank you in advance and hope to see you in 2022!

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.

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

Every week, we will also award surprise prizes for more fun.

Note that MathWorks staff are NOT eligible for prizes.

Q5: How do votes on my entries determine my rank on the leaderboard?

The total number of votes on ALL of your entries determines your rank on the leaderboard.

Q6: Do votes on remixed entries add votes to the original entry?

No. We count only direct votes on an entry.

Q7: Is the code (also) automatically compared to earlier submissions to determine the remix tree?

No. You have to remix an entry.

Just in 2 days since the contest started, we already have 200+ awesome entries in the MATLAB Mini Hack contests. We are excited to see so many talented and creative community members enjoying the contest and learning from each other.

If you haven’t created your entry, try remixing an entry you like. Make some SMALL changes and see what it would look like. Remix is highly encouraged in this contest.

If you haven’t entered the Treasure Hunt contest, give it a try. Your participation will not only win you a prize but also bump up MathWorks’ donation to a charity organization that fights the global pandemic.

Reminder:

  • Voting will start next Monday.

Let's say MathWorks decides to create a MATLAB X release, which takes a big one-time breaking change that abandons back-compatibility and creates a more modern MATLAB language, ditching the unfortunate stuff that's around for historical reasons. What would you like to see in it?
I'm thinking stuff like syntax and semantics tweaks, changes to function behavior and interfaces in the standard library and Toolboxes, and so on.
(The "X" is for major version 10, like in "OS X". Matlab is still on version 9.x even though we use "R20xxa" release names now.)
What should you post where?
Wishlist threads (#1 #2 #3 #4 #5): bugs and feature requests for Matlab Answers
Frustation threads (#1 #2): frustrations about usage and capabilities of Matlab itself
Missing feature threads (#1 #2): features that you whish Matlab would have had
Next Gen threads (#1): features that would break compatibility with previous versions, but would be nice to have
@anyone posting a new thread when the last one gets too large (about 50 answers seems a reasonable limit per thread), please update this list in all last threads. (if you don't have editing privileges, just post a comment asking someone to do the edit)
Is anyone else disappointed with uifigures? It seems apparent that these will eventually replace traditional figures, but there is still so much that doesn't quite work. I've tinkered with uifigures since their introduction in release 2016a, but even in 2020a I can't reliably export a uifigure to a graphics file. Sure it works sometimes, but not if a uipanel is present. The exportgraphics command is not as powerful as the print command, leaving some graphic formats (such as *.svg and *.eps) unsupported. How do you generate graphic files of a specific size? You can't even use subplots without overriding the default AutoResizeChildren setting!
Everything with uifigures seems to be slower and less stable than the figure variant. App Designer is much better than GUIDE, but that is not exactly high praise. I would rather generate "apps" programatically across several files instead of dealing with a single-file class definition containing 1000+ lines.
Where is this transition going? MATLAB graphics are moving away from Java in favor of JavaScript, and I'm not sure that we are at all ready for that.

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.
