As a long-standing request from users, we are happy to announce that HDFql now supports MATLAB for managing HDF5 and MAT files.
In short, HDFql (Hierarchical Data Formal query language) is the first high-level, declarative language for managing HDF5 or MAT data. Designed to be as simple and powerful as SQL, it dramatically reduces the learning effort and time required to work with HDF5. With its intuitive syntax, HDFql provides a clean interface for reading and writing HDF5 data across programming languages (C, C++, Java, Python, C#, Fortran, R, and now MATLAB) and platforms (Windows, Linux, and macOS). In addition, HDFql is based on a flexible parallel architecture that transparently leverages available cores and, in MPI clusters, nodes to efficiently process large volumes of data.
Key benefits of HDFql include enabling users to replace dozens of lines of complex HDF5 code with just a few lines of simple code, helping AI models generate better code using far fewer tokens, and making AI-generated code easier for humans to review.
Happy coding, prompting, or reviewing with HDFql in MATLAB!
We use Timecontrol for statistic automations. Yesterday at 2026-10-220 10:00pm CET Time control stopped working. There is new new time in the "Run At" field, although the script should run every 5 minutes. We had the same problem in September, see https://de.mathworks.com/matlabcentral/answers/2184870-thingspeak-timecontrol-stopped-working-at-all?s_tid=srchtitle
Has anybody also prolems with Timecontrol?
The new installer streamlines the process of installing and setting up agentic workflow with MATLAB. If you have been intimidated by the setup process, give this a try!
https://github.com/matlab/agentic-toolkit-installer
I am frequently facing issue with the onramp training of not proceeding to the next task or section, even after successfully completion of the current task or complete section.
Agentic AI is changing how engineers work. Join Jason Ghidella to see how AI agents can help accelerate coding, modeling, requirements generation, testing, and validation with MATLAB and Simulink, while maintaining the rigor needed to trust the results.
See real-world demonstrations spanning app building, system modeling, simulation, test generation, and system validation, and discover what the future of AI-powered engineering looks like.
For the past several days I have been experiencing a problem with data visualization on two of my ThingSpeak channels.
The data appears to be uploaded and stored correctly, and new entries are still being added to the channels. However, the visualizations are not working correctly.
The standard Field Charts show only a very small number of data points instead of the normal continuous measurements. Most of the points are compressed on the left side of the chart, while one or a few points appear far to the right and are connected by long straight lines. The time axis is also incorrect and sometimes shows repeated dates such as “01 Jan”.
The numeric widgets are affected as well and display incorrect values. Some custom visualizations also remain blank or fail to load.
The problem appeared suddenly and affects two separate channels which had previously been working correctly. I did not make any significant changes to the channels before the problem started.
This seems somewhat similar to the ThingSpeak chart/timeline issue reported in June 2026, when charts were displaying incorrect time ranges and the DAYS/RESULTS settings were not working correctly. However, my current problem also affects numeric widgets and custom visualizations, and the charts show incorrect dates and strangely positioned data points.
Could this be a regression or a similar issue with the ThingSpeak visualization system?
Has anyone else experienced the same problem recently?
The Ran In tag still shows R2026a on Answers and Discussions (as does the Executing In popup), even though both are actually running R2026b.
This seems to be always be an issue whenver the site updates to the latest release. Seems like it should be pretty straightforward to update those message at the same time the underlying release is updated. Or am I underestimating the complexity of that task?

Hello everyone. I am noob at coding and want to learn advance level of matlab and i want a book for me to help me learn from scratch and make sure its well thing and i am mostly interested in mechatronics like how a system acts and behaves so please give me some reccomandation also i am frustated.
What if MATLAB could show you not only the final output, but also how your code reaches that result?
Imagine an interactive tool that visualizes variable changes, function calls, matrix transformations, and execution flow as a program runs. Engineers could watch algorithms evolve, identify unexpected behavior, and understand complex simulations through live visualizations.
The idea is to build a Live MATLAB Execution Explorer that combines code tracing, variable timelines, and 3D engineering simulations in one interface.
From debugging control systems to teaching numerical methods, this could transform how students, researchers, and engineers interact with code.
The challenge? Capturing execution data efficiently without significantly affecting performance.
The vision: Turn programming from something we read into something we can see, explore, and understand.
#MATLAB #Simulink #EngineeringInnovation #Simulation #DeveloperTools
I recently had an idea for a side project: building an app/extension that can interactively follow simulations and visualise the live flow of code execution.
For this, I would need access to variables, datasets, and the function call stack during execution, ideally without interfering with the actual code execution.
However, I found that MATLAB's current architecture makes this difficult, as the entire application runs in a single thread and there are no publicly exposed APIs to access runtime variables without interrupting execution.
Can anyone suggest a possible workaround or an alternative approach to achieve this?

Hello everyone
After you read the blog post about all the new goodness in MATLAB 2026b I am sure you'll rush out to install it. If you do one more thing, however, I suggest that you install this add-on from MATLAB File-Exchange since it will make object-oriented code much faster.
"How much faster?" I hear you ask. This much faster:
If you prefer numbers to pictures, all of the details are in a blog post from when we released the limited beta: Objects are about to get much faster in MATLAB » The MATLAB Blog - MATLAB & Simulink
"Why didn't we make this the default?" I hear you ponder. Because there is a small chance that the new system will break your code. It's a very small chance and I've personally not seen any code that does get broken. However, such code does exist and we want to be give you the chance to discover this and work with us to make your code compatibile before it does become the default.
I hope you enjoy using 2026b as much as we enjoyed making it.
Cheers,
Mike

Hey, this is a safe space to share your cool projects you know. I have pet ducks, I use ThingSpeak to open the door to their house each morning. I just finished an upgrade to the LED strip lights on my driveway that are controlled via ThingSpeak. And the valves for my drip irrigation system. You got it. Controlled by ThingSpeak. Let me know your last cool project you finished or the one you keep dreaming of starting. I need some more inspiration :)
I contributed a guet post for @Mike Croucher - AI Agent Demystified – Building a Minimalist Agent in MATLAB
Basically, my use case is an coding agent built with MATLAB to code MALTAB, but you can actually roll your own agnet with MATLAB AI Agent SDK for more realistic use cases. Hopefully my post gives you a starting point for a fun exploration!
