Memory usage constantly growing: efficient RAM usage in my script?

Hello,

I have a very long running MATLAB script working with variables which use 1 GB storage if I save them on harddisk with the save() command. The process goes like this: - calculating values - save values to file (1 GB) - repeat everything in a loop using the old variables

So I reuse my variables every loop iteration, but my RAM usage is constantly growing and at some point exceeds my memory and MATLAB crashes.

So my questions is: Is my process efficient with reusing my variables? I am wondering why my RAM usage is constantly growing.

Any help is welcome!

Without seeing the relevant part of the code, guessing the reasons for this behaviour is impossible.

You should check whether the re-used variables are changing size.
