The only reason I was asking is:
We run a 'simple simulation' with very large matrices, the final precision
is (not yet) very important.
Matlab runs the program perfectly, but we only have a licence for Windows
and not for linux.
Therefore it would be nice to use octave, to me it seems to be a powerfull
Running the the simulation using octave gives a Memory exhausted error,
although the same program is only using 750 Mb using Windows NT 4.0 (on a 1
GB system).
I know I can change the source code of my program, store a tmp-file and what
so ever,
I only want to have a fast solution to run the simulation using linux.

Thank you for the suggestions you made, but I already was aware of that.

Look at the mailing-list for 16-3 and 17-3, some-one has the same
allocation problems as I do have using linux (Redhat 6.1)
