"Function MEMORY is not available on this platform."

I followed

and ran a command memory but got the following outcome

Error using memory

As stated in the Limitations section on the documentation page for the memory function, this function is only supported on Microsoft Windows systems.

Thank you. Is there any way to know for Linux version?

Not sure if the functionality is identical, but the following call to java will give you a number that matches up with the Java heap memory that is set in preferences:

runtime = javaMethod('getRuntime', 'java.lang.Runtime');
maxMemory = javaMethod('maxMemory', runtime);

[Walter Roberson]

If I recall, on Linux you would want to first find your process ID, and then example the /proc file system entry for that process, as that can tell you how much memory the process is using.
