MathWorks release MATLAB MCP Core server
In the video below you are watching Claude read a file on my local machine and use my local install of MATLAB to analyze it. Claude writes the MATLAB code,puts it on my machine and runs it using my copy of MATLAB

Don't do this....
matlab -nodisplay -nosplash -nodesktop -r "myscript;exit"
Do this
matlab -nodisplay -batch myscript

I originally paired my iPhone with an Apple Watch. It was seamless, beautiful, functional…in loved it!
Battery sucked though. I wasn’t even sorry when this happened, it gave me an excuse to ditch it.

I held a Samsung Galaxy Z Fold 7 recently and it was the first time in years that I had genuine gadget lust. I really wanted it!
I moved from android to iPhone a few years ago solely for improved battery life but this almost made me go back….almost.

In my day, '42' was the number we'd try to force into everything. Want to see a random number generator? '42'
Choose a number between 1 and 100? '42'
Now it seems to be 67 and I have no idea why!

The MATLAB documentation is pretty great and now we've sprinkled a little (but not too much!) AI over it. The result works well! Check out the details in my latest article

While on vacation to Mexico this year i discovered tamarind candies such as the one in the picture and now I’m obsessed!
Need to find a source in the UK as I’m running low on supplies.

Software testing in MATLAB is easier to do and better than ever. If you want to get started, then check out this recent video tutorial that one of my colleagues delivered as part of the HiRSE seminar series on testing cc @helmholtzosoffice.bsky.social #RSE

Last week I ditched my Apple Watch for a Garmin Fenix 8 after the Apple Watch face popped off following a very gentle swim.
The Garmin Fenix 8 is fantastic. Worth the switch for battery life alone. Battery life measured in weeks vs hours for the apple watch.
Any other Garmin fans here?

I've just watched a presentation about what's new in version 6 of OpenMP.
Quite interested in the loop transformations that can do things like tiling, loop unrolling etc with compositions of them all. No more screwing up of indices while trying these things out

If you are a #MATLAB user running parallel code (e.g. it uses parfor, parfeval etc) then give this trick a try.
When you open your parallel pool, do it like this
parpool("Threads")
Best case: Your code runs faster and uses less memory
Details in my article: blogs.mathworks.com/matlab/2025/...

Nervously waiting to begin the first MathWorks webinar I've developed since starting my new role as Developer Advocate
Starts in 5 minutes and apparently this one has over 1600 people signed up!
Giving it again this evening (UK time) to another 1200 or so. There's still time to sign up!
