Thanks @Yann Debray

Introduced in...

A colleague said that you can search the Help Center using the phrase 'Introduced in' followed by a release version. Such as, 'Introduced in R2022a'. Doing this yeilds search results specific for that release.
Seems pretty handy so I thought I'd share.
Unlike last year's contest, there are some new technologies this year that might offer some advantages. Namely generative AI's like ChatGPT, Bard, etc. Not to be excluded, MathWorks just launched the AI Chat Playground :)

Here's a link to this years animation contest.
Here's a MATLAB class I wrote that leverages the MATLAB Central Interface for MATLAB toolbox, which in turn uses the publicy available Community API. Using this class, I've created a few Favorites that show me what's going on in MATLAB Central - without having to leave MATLAB 🙂
The class has a few convenient queries:
  • Results for the last 7 days
  • Results for the last 30 days
  • Results for the current month
  • Results for today
And supporting a bunch of different content scopes:
  • All MATLAB Central
  • MATLAB Answers
  • Blogs
  • Cody
  • Contests
  • File Exchange
  • Exclude Answers content
The results are displayed in the command window (which worked best for me) and link to each post. Here's what that looks like for this command
>> CommunityFeed.thisMonth("app designer", CommunityFeed.Scope.ExcludeAnswers)
Let me know if you find this class useful and feel free to suggest changes.
Hi all,
I am wondering whats the total cost to use MATLAB for algo trading. The transparent part is of coz the price of matlab and the toolboxes. But I was shocked to find out the APIs to connect to Interactive Brokers are not free (costly in fact!). Is there free API to connect to IB? What other hidden costs are there? I saw the X Trader in the Automated Trading with MATLAB video. Is this XTrader software part of MATLAB toolbox? Do we need to pay additional to Trading Technologies (to use X_Trader). Also what data feed is the most cost effecient? Is there any additional hidden cost that I am not aware of?
Thanks!

Use of Wild Cards to search channels

We operate roughly 600 data loggers on Think Speak where there are roughly 150 gateways and each gateway communicates with a node. Our channels are labeled node# - gateway number and each number is 16 diigits. We have not found a wildcard search function so must have each number exactly right or we cannot find our channel. In some cases we wish to query a gateway and see which nodes are successfully communicating with it.

Regarding Recent Spam Attacks

Over the past several months our communities have been the target of ongoing spam attacks. Spam is a common issue online and spam prevention is something we include as part of our standard development processes. The most recent attempts appear to be specifically targeting our sites with a combination of manual and automated attacks, probing with a variety of content attempting to bypass our filters. Regrettably, the attacks sometimes make it through our defenses, cluttering your inboxes and the content in our communities.

Rest assured, we are dedicated to continuing to evolve our tools and improve our capabilities to meet the goal of eliminating all spam in our communities. We appreciate your patience and understanding as we work to get there.

Sincerely,

David Wey
