This is outside the scope of Octave, this is more of an operating system
question that would apply to any program.

On a Linux system, I would create a memory-backed file by writing to and
reading from a file under either the /dev/shm or the /run directories.

I guess from your earlier post that you are using macOS. I have no idea
whether that operating system has a memory-based filesystem or another
means of creating and working with files in memory rather than on disk.
