Also on the team here. Feel free to ask any questions — we’ll be monitoring this thread for the next few hrs! Curious what other’s views on DSLs are post-LLMs too

Why not a shared buffer? Serializing into JSON on this hot path should be entirely avoidable

Appreciate the comment actually! It's good feedback -- we weren't sure if it's mixing work/memes too much, and keeping our materials clean like engineering docs are probably a good way to go. We may edit it out of the po

It's open source / free. But yes, of course we want people to try it and get value from it.

Seeing in MATLAB code how ode45 is implemented != how the thing is running on the machine. That's a very small top slice. But okay -- as I mentioned, you're entitled to your views!

Shameless plug for RunMat (we wrote this blog article, also an open source alternative for MATLAB): https://runmat.org

Yep -- Octave was very helpful for me in school. Octave is not particularly fast. RunMat is very fast (orders of magnitude -- see benchmarks).

>> The engine is closed source. You cannot see how fft or ode45 are implemented under the hood. For high-stakes engineering, not being able to audit your tools is a risk. This is just a lie. Open matlab and you can inspect all the imp

If the rewrite is for performance, ideally the logic capture = the thing executing in production. Cases where a JIT running would conflict with requirements notwithstanding (e.g. HIL with strict requirements and whatnot)...

Yep! Makes sense. Though I think the cost of writing these toolboxes is lim --> 0. Will have a really solid rust inspired package manager soon, and a single #macro to expose a rust function in the RunMat script's namespace (= easy t

In Julia, you explicitly need to still reason about and select GPU drivers + manage residency of tensors; in RunMat we abstract that away, and just do it for you. You just write math, and we do an equivalent of a JIT to just figure out when

@mNovak -- super helpful note! Thank you! Author of RunMat (this project) here -- > The first thing they teach about performant Matlab code is that simple for-loops will tank performance. Yes! Since in RunMat we're building a comput

Thanks!! It was originally for Octave users whose scripts were running painfully slow. The goal was to keep the MATLAB frontend capture syntax, but run it fast. When we dug into why people were still using Octave, it was because it let th

a solid core, not the whole Matlab (they confound the language, compiler / runtime, an IDE, and a bunch of other things in the name / product that is MATLAB). This is a solid compiler + minimal runtime, with an architecture design

Versus Octave: - Lots of language semantics are unsupported in Octave (like Classes), and it’s purely a slow line by line interpreter so it’s very slow. - Given the design / Cranelift IR translation here, RunMat can run natively on any
