Thread Subject: clear all does not clear all memory?

Hi all,

I've been running some simple, but quite lengthy calculations in Matlab (R14).

In order to save RAM, for each cycle, variables are cleared by a "clear all" command.

But this does not solve everything, since I can tell by the Windows task manager that memory is still taken by Matlab (wich can exceed 1.5 GB) even after my program has crashed or ended, and even if I cleared all variables with a "clear all". Memory is only freed if I shut down matlab and restart it.

Is there any command that really clears all the cache?

Thank you!

I don't know whether this will fix your problem but you could try
running the PACK command after CLEAR ALL.

Hi, thanks for the reply.

The pack command did not directly solve the problem, but helped me reach documentation that addresses this.

No real solution, as this seems to be related to Win32 platform memory management. I actually solved this by using the matlab compiler and running the exe file. No more memory problems.

Cheers,
