Interpreted languages can be seen as a variation in assembler running on an emulated kernel. They have stacks and commands that work just like assembler, without actually being assembler. This is a virtual machine.
A for a cycle can be considered as an indication to the system, setting a value, performing a sequence of tasks, and when you are done, return and check this value. If it is not on the threshold, change it in the established order and repeat these tasks and return. In assembler, you run fast, but not so much in VM.

This means that what seems to be a for loop is not really a for loop. These are operating system interrupts and virtual memory. This is a virus scan in the background and a megastar.
If you had a virtual system, you could make a reduction for addressing memory that didn't use a virtualized loop, which was reasonably efficient? MatLab is trying to handle data processing, so it must have very efficient ways to store, sort, and select data on its virtual machine.
MathWorks does not intend to make this publicly available. If he has a great idea, they don’t want it to be implemented in Python and R tomorrow. If he has a mediocre idea, then they don’t want to be beaten by Python and R tomorrow. In any case, making the nuts and bolts of this particular approach available to the public without an NDA is most likely a lost proposition for them.
Bottom lines:
- this is not a real "for", even for a for loop, because it actually works
- they open some of the internal parts of data processing to improve usability.
- they are unlikely to disclose the actual code due to negative business consequences.
It is worth noting that vectorized code can excel for loops by doing the same. This means that they are likely to use more of these internal components to carry out a "task sequence" to increase productivity.
