matlab "memory" function on mac?

Question

On Windows machines, MATLAB users can use either the memory or the feature memstats commands. However, neither of these work on a machine, failing as follows:

>> memory
??? Error using ==> memory
Function MEMORY is not available on this platform.

>> feature memstats
??? Error using ==> feature
An unknown feature was specified

Does anyone know of a way to access information about in-matlab memory usage on a Mac?

Answer 1

I have not been able to find a command that reproduces the functionality of memory. However, if you know how much total memory your system has, you can use who (or vsize from the file exchange for more detail) to estimate how much memory your variables are currently using and thus how much free space you have.

By the way, you can always find out about Java memory by calling

java.lang.Runtime.getRuntime.maxMemory
java.lang.Runtime.getRuntime.totalMemory
java.lang.Runtime.getRuntime.freeMemory

Note that Matlab memory and Java memory are different - Java memory is used for UI, including figures, as well as other java objects, while memory reports the memory available for variables and calculations.
