Does MATLAB also compete in the same field?

MATLAB/Simulnk is imperative. They have signal flow/causal approach. So you should know ahead of time which variable causes another variable to change i.e. which is defined first.

Modelica is acausal. You define the variables and how they are related (equations). The compiler handles variable dependencies and resolution internally.

There are pros & cons of each. Both are used for simulating cyber-physical systems.

I seem to have a problem understanding "acausal". Is its meaning "not causal"? To me that wouldn't make much sense and sounds like another buzzword. The software still runs inside a computer. Everything inside of it is causal. And nust because the compiler decides in what order to do what, that also doesn't make it not causal, since surely the compiler follows some well known rules that _cause_ it to decide this way or that way. And surely defining relations _is_ in a way defining the causal ... relations.

So what is really the meaning of "acausal" in this context?

Sounds like Simulink to me, which is one of the major MATLAB programming environments.

ETA: Apparently MathWorks has Simscape in this category.

And Mathematica has this: https://www.wolfram.com/system-modeler/

I would love to use Modelica but in my field Simulink is king
