Hi everyone
My blog post about the latest MATLAB release was published yesterday MATLAB R2026a has been released – What’s new? » The MATLAB Blog - MATLAB & Simulink
There are a lot of new features and performance enhancements and from conversations I've had across several social media platforms., it seems that the new metafunction functionality is emerging as a user favourite. What are you most excited to see?
Cheers,
Mike
Hi,
I am trying to use an esp32 board with quectal ec200u LTE Modem to send sensor data to thingspeak. The board can process the sensor data however I am unable to send the data to thingspeak. I have used the same process earlier too however with a different modem from Simcom.
Can someone help me with specific commands for achieving this? I can share the code which i am trying to use.
Regards
Aditya
Good morning everyone. I’m having a problem with ThingSpeak. I’m sending data from an ESP LoRa with the RTC set to the Brasília time zone (GMT-3).
Previously, when I exported the data to CSV, it used the ThingSpeak time, which appeared 3 hours ahead. Now that I’m sending the timestamp from the ESP, the graphs are showing the data 3 hours behind. Is there a way to align the graph times while keeping the Brazilian time zone?
I have been a loyal MATLAB user for 25 years, starting from my university days. While many of my peers migrated to Python, I stayed for the stability, compatibility, and clean environment. However, I am finding the 2025 version exceptionally laggy. Despite running it on an $10k high-end machine, simple tasks like viewing variables and plotting take up to 60 seconds - actions that were near instantaneous in the 2020 version. I want to stay continue with MATLAB, but this performance gap is a major hurdle and irritation. I hope these optimization issues can be addressed quickly.
Short version: MathWorks have released the MATLAB Agentic Toolkit which will significantly improve the life of anyone who is using MATLAB and Simulink with agentic AI systems such as Claude Code or OpenAI Codex. Go and get it from here: https://github.com/matlab/matlab-agentic-toolkit

Do we know if MATLAB is being used on the Artemis II (moon mission) spacecraft itself? Like is the crew running MATLAB programs? I imagine it was probably at least used in development of some of the components of the spacecraft, rockets, or launch building. Or is it used for any of the image analysis of the images collected by the spacecraft?
MATLAB interprets the first block of uninterupted comments in a function file as documentation. Consider a simple example.
% myfunc This is my function
%
% See also sin
function z = myfunc(x, y)
z = x + y;
end
Those comments are printed in the command window with "help myfunc" and displayed in a separate window with "doc myfunc". A lot of useful things happen behind the scenes as well.
- Hyperlinks are automatically added for valid file names after "See also".
- When dealing with classes, the doc command automatically appends the comment block with a lists of properties and methods.
All this is very handy and as been around for quite some time. However, the doc browser isn't great (forward/back feature was removed several versons ago), the text formatting isn't great, and there is no way to display math.
Although pretty text/math can be displayed in a live document, the traditional *.mlx file format does not always play nice with Git and I have avoided them. However, live documents can now (since 2025a?) be saved in a pure text format, so I began to wonder if all functions should be written in this style. Turns out that all you have to do is append these lines:
%[appendix]{"version":"1.0"}
%---
to the end of any function file to make it a live function. Doing so changes how MATLAB manages that first comment block. The help command seems to be unaffacted, although [text] may appear at the start of each comment line (depending on if the file was create as a live function or subsequently converted). The doc command behaves very different: instead of bringing up the traditional window for custom documentation, the comment block looks like it gets published to HTML and looks more similar to standard MATLAB help. This is a win in some ways, but the "See also" capabilitity is lost.
Curiously, the same text can be appended to the end of a class definition file with some affect. It does not change how the file shows up in the editor, but as in live functions, comments are published when using the doc command. So we are partway to something like a "live class", but not quite.
Should one stick with traditional *.m files or make everything live? Neither does a great job for functions/classes in a namespace--references must explicitly know absolute location in traditional functions, and there is no "See also" concept in a live function. Do we need a command, like cdoc (custom documentation), that pulls out the comment block, publishing formatted text to HTML while simultaneously resolving "See also" references as hyperlinks? If so, it would be great if there were other special commands like "See examples" that would automatically copy and then open an example script for the end user.

PLEASE, PLEASE, PLEASE... make MATLAB Copilot available as an option with a home license.
Please change the documentation window (https://www.mathworks.com/help/index.html) so I don't have to first click a magnifying glass before I can to get to a text field to enter my search term.
Matlab seems to follow a rule that iterative reduction operators give appropriate non-empty values to empty inputs. Examples include,
sum([])
prod([])
all([])
any([])
Is it an oversight not to do something similar for min and max?
max([])
For non-empty A and B,
max([A,B])= max(max(A), max(B))
The extension to B=[] should therefore satisfy,
max(A)=max(max(A),max([]))
for any A, which will only be true if we define max([])=-inf.

If you have published add-ons on File Exchange, you may have noticed that we recently added a new, unique package name field to all add-ons. This enables future support for automated installation with the MATLAB Package Manager. This name will be a unique identifier for your add-on and does not affect the existing add-on title, any file names, or the URL of your add-on.
📝 Update and review until April 10
We generated default package names for all add-ons. You can review and update the package name for your add-ons until April 10, 2026. Review your package names now:
After April 10, you will need to create a new version to change your package name.
🚀 More changes coming with the MATLAB R2026b prerelease
Starting with the MATLAB R2026b prerelease, these package names will take effect. At that time, the package name may appear on the File Exchange page for your add-on.
Keep your eyes peeled for exciting changes coming soon to your add-ons on File Exchange!
Cantera is an open-source suite of tools for problems involving chemical kinetics, thermodynamics, and transport processes. Dr. Su Sun, a recent graduate from Northeastern Chemical Engineering Ph.D. program made significant contributions to MATLAB interface for Cantera in Cantera Release 3.2.0 in collaboration with Dr. Richard West, other Cantera developers, and MathWorks Advanced Support and Development Teams. As part of this Release, MATLAB interface for Cantera transitioned to using the new MATLAB- C++ interface and expanded their unit testing. Further information is available here.
I began coding in MATLAB less than 2 months ago for a class at community college. Alongside the course content, I also completed the MATLAB onramp and introduction to linear algebra self-paced online courses. I think this is the most fun I've had coding since back when I used to make Scratch projects in elementary school. I'm kind of curious if I could recreate some of my favorite childhood Scratch games here.
Anyways, I just wanted to introduce myself since I plan to be really active this year. My name is Mehreen (meh like the meh emoji from the Emoji movie, reen like screen), I'm a data science undergrad sophomore from the U.S. and it's nice to meet you!
Hi everyone,
Some of you may remember my earlier post. Quick version: I'm a biomed PhD student, I use MATLAB daily, and I noticed that AI coding tools often suggest functions that don't exist in R2025b or use deprecated ones. So I built skills that teach them what actually works.
v2.0 adds 54 template `.m` scripts, rewrites all knowledge cards based on blind testing, and verifies every function call against live MATLAB. I tested each skill on 17 prompts and caught 8 hallucinated functions across 5 toolboxes (Medical Imaging, Deep Learning, Image Processing, Stats-ML, Wavelet).
Give it a spin!
Repo: matlab-toolbox-skills
The skills follow the Agent Skills open standard, so they also work with Codex, Gemini CLI, Claude Code and others. If you use the official Matlab MCP Server from MathWorks, these skills complement it: the MCP server executes your code, the skills help the AI write good code to begin with.
One ask
How do we measure performance and evaluate agent skills? We can run blind tests and catch hallucinated functions, but that only covers what we thought to test. The honest answer is that the best way to evaluate these is community consensus and real-world testimonials. How are you using them? What worked? What still broke?
Your use cases and feedback are the most reliable eval I can get, and as a student building this, they're also the real motivation for me to keep going. If a skill saved you from a hallucinated function or pointed you to the right function call, I'd love to hear about it. If something is still wrong, I need to hear about it.
Issues, PRs, or just a reply here. Star the repo if it saved you time.
Thanks!
Happy Spring! and Happy Coding in Matlab!
Best,
Ritish
