List all environment variables in Matlab

Question

How does one get a list of all defined environment variables in Matlab? I'm aware of getenv but you have to provide a name, and doc getenv offers no help in how to use it to retrieve items in any other way. I can't find any other relevant information online. Is this even possible?

I'm interested in a platform-independent answer (or at least Windows and Linux).

Answer 1

You could use

system('env')

on linux/mac, and

system('set') % hope I remember correctly, no windows at hand

In both cases you'd have to parse the output though, as it comes in the format variable=<variable-value>.
