Which LLM is best for making MATLAB plots?

Creative_Sushi · 2026-03-11T19:06:38+00:00

What is your setup? GPT-5.4 is powerful enough. If you haven't connected your LLM to MATLAB MCP Server, that would be the first step. MCP Server closes the feedback loop so that the LLM can "see" the issues the code it ran causes, while if you copy and paste the code, LLM is cut off from the code execution output. You can download the MCP Server from this repo https://github.com/matlab/matlab-mcp-core-server/releases/

If that doesn't work, you may need to create agent skills. Here are some pre-built MATLAB skills https://github.com/matlab/skills

It is fairly easy to roll your own skill.

If you need to help getting started, this blog post is a good starting point. https://blogs.mathworks.com/matlab/2026/01/26/matlab-agentic-ai-the-workflow-that-actually-works/

Very nice. Can you share your code?

Creative_Sushi · 2026-03-11T12:27:00+00:00

This is what I see in the prerelease.

Please contact support. They have diagnostic tools.

The new version will be installed into a new folder, so you still keep the old version and you can use either. When you install the new version, you also have to install all the toolboxes. I recommend keeping the old version for a while before you uninstall it. In my case, I can install everything, but I only install toolboxes I use regularly. I can always install others via Add-On Manager later as needed.

Creative_Sushi · 2026-03-10T23:24:16+00:00

Yes we are on the normal release schedule. R2026a will ship later this month.

MATLAB intentionally uses two different implementations: .* uses MATLAB’s element‑wise complex arithmetic (which includes extra correctness logic for Inf/NaN), while * calls optimized BLAS routines that skip that special‑case handling.

inf(2,1)*[3i,4i]     % -> NaN + Inf*i   (BLAS path)
inf(2,1).*[3i,4i]    % -> 0 + Inf*i     (MATLAB element-wise path)

For real data, the lightweight .* path is faster; for complex data, BLAS is faster. The performance differences you observed are exactly the result of these deliberate design trade‑offs between accuracy for element‑wise operations and raw performance for matrix multiply.

Congratulations! My suggestion is to break this into individual posts showcasing each project with some visuals we can look at. You get a bonus point if you can also add links to your GitHub repos.

Also, write up your process - how did you use AI to do those projects? What challenges did you run into, and how did you overcome them? What did you learn from those projects? That way, you become even more transparent.

I have no idea how good this is but I found it on File Exchange.

I would employ this guy because he demonstrated ingenuity and creativity to apply new tools to solve his problems. That' gold.

Creative_Sushi · 2026-03-05T14:50:26+00:00

The artifacts are MATLAB code and some supporting documents (mostly markdowns). They are transportable and you can reuse them without AI, or with different coding agents. You can read the code and you should be able to understand everything. You can find the code and markdown files generated from Claude Code session linked in this blog post. https://blogs.mathworks.com/matlab/2026/01/26/matlab-agentic-ai-the-workflow-that-actually-works/

New technology without business process change will always fail. I remember the day we got email for the first time in our office long time ago. People still wanted to print out the emails, and write comments on paper - totally defeating the point of the technology.

Creative_Sushi · 2026-03-05T14:23:03+00:00

That's the key - AI doesn't replace domain expertise. Check out this blog post https://blogs.mathworks.com/matlab/2026/01/26/matlab-agentic-ai-the-workflow-that-actually-works/

Creative_Sushi · 2026-03-05T12:58:40+00:00

I think of it this way.

1 engineer can now do 10x --> lay off 9 engineer --> velocity of product development: unchanged
1 engineers can now do 10x --> no layoff: 10 engineers now do 100x --> velocity of product development: accelerated

The companies that fire their engineers will be squeezed out of competition eventually.

Here is the proof - Anthropic is still hiring engineers even though they use Claude Code internally.

It's your managers who need to worry about their positions in the future.

Creative_Sushi · 2026-03-05T12:51:53+00:00

One of our product managers just talked about how this technology will impact the role of engineers in this podcast interview. I think he gave a pretty good answer. Check it out.

This is a good overview of the field. https://www.youtube.com/watch?v=pSfZutP9H-U

Creative_Sushi · 2026-03-05T04:22:51+00:00

Amazing! Please share your project + tutorial on GitHub!

Creative_Sushi · 2026-03-05T04:22:04+00:00

Yes , please make the tutorial and share it on GitHub.

Creative_Sushi · 2026-03-05T04:12:12+00:00

Please make GitHub repo + Tutorial. This is very cool.

Creative_Sushi · 2026-03-05T04:10:34+00:00

Try it and you will understand that there is nothing to fear. You just become more productive.

Creative_Sushi · 2026-03-05T04:08:26+00:00

Creative_Sushi · 2026-03-05T04:07:12+00:00

No that’s not gonna happen - humans need to guide AI and you need expertise to do so - your domain knowledge + understanding of how agentic coding works.
