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.

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
Dear all,
Recently I started working on a VS Code-style integrated terminal for the MATLAB IDE.
The terminal is installed as an app and runs inside a docked figure. You can launch the terminal by clicking on the app icon, running the command integratedTerminal or via keyboard shortcut.
It's possible to change the shell which is used. For example, I can set the shell path to C://Git//bin//bash.exe and use Git Bash on Windows. You can also change the theme. You can run multiple terminals.
I hope you like it and any feedback will be much appreciated. As soon as it's stable enough I can release it as a toolbox.
What’s New in MATLAB and Simulink in 2025
If you missed this session live, this is one of those “everyone’s talking about it” updates you’ll want to catch up on. 👀
This session is packed with the kinds of enhancements that quietly (and not so quietly) change how you work every day.
Here’s why it earned a spot in our Top 4:
- A redesigned MATLAB desktop with customizable sidebars and light/dark themes—built to adapt to how you work
- New side panels for coding and development tasks, plus more control over organizing and customizing figures
- MATLAB Copilot, a generative AI assistant optimized for MATLAB to help you explore ideas, learn techniques, and boost productivity directly in the desktop
- Simulink workflow improvements like a redesigned Simulink scope, more detailed info in quick insert, and automatic signal line straightening
- Enhanced Python integration across MATLAB and Simulink
- New AI deployment options optimized for Qualcomm and Infineon hardware targets
If staying current with MATLAB and Simulink is part of your role—or your edge—this session is a must‑watch. Missing it means missing context for features that will shape how you work in 2026 and beyond.
💬 Discussion topic:
Which single update from this release do you think will most improve your day‑to‑day workflow, and why?
A Live Script can be converted to an HTML5 framework web application with AI as described in Double Pendulum Chaos Explorer: From HTML5 Prototype to MATLAB interactive application with AI. I have recently provides converted the Live Script Classical Stark Effect to a web application supporting a 3D twirlable display of motion of a particle subject to an inverse square law force plus an additional constant force - the problem known as the classical Stark effect.
The web application deployed to GitHub may be launched here and documents its dependencies below the interactive application. The files are available at Classical Stark Effect — Interactive Web Simulation. One gotcha was the need to enable hardware acceleration in Chrome (no problem in Safari) to support a 3D twirlable display. If hardware acceleration is disabled in Chrome, the application provides a warning and replaces the 3D twirlable display with a 2D alternate.
The conversion of the script to a web application was performed with Perplexity.ai. The GitHub deployment was accomplished with Anthropic's Claude using the open source GitHub CLI. WIth the gh CLI (already installed and authenticated on my Mac) via osascript, and Claude connected to my file system via MCP and an ngrok server, Claude executed on my Mac the following sequence of steps:
1. git init
Creates a hidden .git/ directory in the staging folder, initializing it as a local git repository. Before this command the folder is just a plain directory; after it, git can track files there. Run once per new project.
2. git branch -M main
Renames the default branch to main. Older git versions default to master; GitHub now expects main. The -M flag forces the rename even if main already exists. Must run after git init and before the first commit.
3. git add -A
Stages all files in the directory tree for the next commit. The -A flag means "all" -- new files, modified files, and deleted files are all included. This does not write anything to GitHub; it only updates git's internal index (the staging area) on your local machine.
4. git commit -m 'Initial release: Classical Stark Effect Interactive Simulation'
Takes everything in the staging area and freezes it into a permanent commit object stored in .git/. This is the snapshot that will be pushed. The -m flag provides the commit message inline. After this command, git knows exactly what files exist and what their contents are -- gh repo create --push will send exactly this snapshot.
5. gh repo create ClassicalStarkEffect --public --source=. --push
Three things happen in sequence inside this one command:
- gh repo create ClassicalStarkEffect --public -- calls the GitHub API to create a new empty public repository named ClassicalStarkEffect under the authenticated account (DuncanCarlsmith).
- --source=. -- tells gh to treat the current directory as the local git repo. It reads .git/ to find the commits and configures the remote.
- --push -- sets the new GitHub repo as origin and runs the equivalent of git push origin main, sending the commit from step 4 up to GitHub.
Without steps 1-4 having run first, --push would have nothing to send and the repo would land empty.
6. gh api repos/DuncanCarlsmith/ClassicalStarkEffect/pages --method POST -f build_type=legacy -f source[branch]=main -f 'source[path]=/'
Calls the GitHub REST API directly to enable GitHub Pages on the repo. Breaking down the flags:
- --method POST -- this is a create operation (not a read), so it uses HTTP POST.
- -f build_type=legacy -- critical flag. Tells GitHub to serve files directly from the branch. The alternative (workflow) would expect a .github/workflows/ Actions file to build and deploy the site, which doesn't exist here, and would produce a permanent 404.
- -f source[branch]=main -- serve from the main branch.
- -f 'source[path]=/' -- serve from the root of the branch (as opposed to a /docs subdirectory).
This is the API equivalent of going to Settings > Pages in the GitHub web UI and setting Branch: main, Folder: / (root), clicking Save.
7. curl -s -o /dev/null -w "%{http_code}" https://duncancarlsmith.github.io/ClassicalStarkEffect/
Not a git or gh command, but the verification step. GitHub Pages takes ~60 seconds to build after step 6. This curl fetches the live URL and prints only the HTTP status code (-w "%{http_code}"), discarding the body (-o /dev/null) and suppressing progress output (-s). 200 means live; 404 means still building.

The session also highlights how Model‑Based Design leverages AURIX TC4x features such as the PPU and CDSP to deploy AI with confidence.
Featuring: Dr. Arthur Clavière, Collins Aerospace
How can we be confident that a machine learning model will behave safely on data it’s never seen—especially in avionics? In this session, Dr. Arthur Clavière introduces a formal methods approach to verifying maching learning generalization. The talk highlights how formal verification can be apploied toneural networks in safety-critical avionics systems.
💬 Discussion question:
Where do you see formal verification having the biggest impact on deploying ML in safety‑critical systems—and what challenges still stand in the way?
Join the conversation below 👇
I was reading Yann Debray's recent post on automating documentation with agentic AI and ended up spending more time than expected in the comments section. Not because of the comments themselves, but because of something small I noticed while trying to write one. There is no writing assistance of any kind before you post. You type, you submit, and whatever you wrote is live.
For a lot of people that is fine. But MATLAB Central has users from all over the world, and I have seen questions on MATLAB Answers where the technical reasoning is clearly correct but the phrasing makes it hard to follow. The person knew exactly what they meant. The platform just did not help them say it clearly.
I want to share a few ideas around this. They are not fully formed proposals but I think the direction is worth discussing, especially given how much AI tooling MathWorks has built recently.
What the platform has today
When you write a post in Discussions or an answer in MATLAB Answers, the editor gives you basic formatting options. Code blocks, some text styling, that is mostly it. The AI Chat Playground exists as a separate tool, and MATLAB Copilot landed in R2025a for the desktop. But none of that is inside the editor where people actually write community content.
Four things are missing that I think would make a real difference.
Grammar and clarity checking before you post
Not a forced rewrite. Just an optional Check My Draft button that highlights unclear sentences or anything that might trip a reader up. The user reviews it, decides what to change, then posts.
What makes this different from plugging in Grammarly is that a general-purpose tool does not know that readtable is a MATLAB function. It does not know that NaN, inf, or linspace are not errors. A MATLAB-aware checker could flag things that generic tools miss, like someone writing readTable instead of readtable in a solution post.
The llms-with-matlab package already exists on GitHub. Something like this could be built on top of it with a prompt that includes MATLAB function vocabulary as context. That is not a large lift given what is already there.
Translation support
MATLAB Central already has a Japanese-language Discussions channel. That tells you something about the community. The platform is global but most of the technical content is in English, and there is a real gap there.
Two options that would help without being intrusive:
- Write in your language, click Translate, review the English version, then post. The user is still responsible for what goes live.
- A per-post Translate button so readers can view content in a language they are more comfortable with, without changing what is stored on the platform.
A student who has the right answer to a MATLAB Answers question might not post it because they are not confident writing in English. Translation support changes that. The community gets the answer and the contributor gets the credit.
In-editor code suggestions
When someone writes a solution post they usually write the code somewhere else, test it, copy it, paste it, and format it manually. An in-editor assistant that generates a starting scaffold from a plain-text description would cut that loop down.
The key word is scaffold, not a finished answer. The label should say something like AI-generated draft, verify before posting so it is clear the person writing is still accountable. MATLAB Copilot already does something close to this inside the desktop editor. Bringing a lighter version of it into the community editor feels like a natural extension of what already exists.
A note on feasibility
These ideas are not asking for something from scratch. MathWorks already has llms-with-matlab, the MCP Core Server, and MATLAB Copilot as infrastructure. Grammar checking and translation are well-solved problems at the API level. The MATLAB-specific vocabulary awareness is the part worth investing in. None of it should be on by default. All of it should be opt-in and clearly labeled when it runs.
One more thing: diagrams in posts
Right now the only way to include a diagram in a post is to make it externally and upload an image. A lightweight drag-and-drop diagram tool inside the editor would let people show a process or structure quickly without leaving the platform. Nothing complex, just boxes and arrows. For technical explanations it is often faster to draw than to write three paragraphs.
What I am curious about
I am a Data Science student at CU Boulder and an active MATLAB user. These ideas came up while using the platform, not from a product roadmap. I do not know what is already being discussed internally at MathWorks, so it is entirely possible some of this is in progress.
Has anyone else run into the same friction points when writing on MATLAB Central? And for anyone at MathWorks who works on the community platform, is the editor something that gets investment alongside the product tools?
Happy to hear where I am wrong on the feasibility side too.
AI assisted with grammar and framing. All ideas and editorial decisions are my own.
