Octave and memory limit?

[Matthieu Debailleul]

Hi,
i use octave-2.1.71 on a linux box with 2.6.12 kernel and 4 Go.
My problem is simple :
i'd like to work with "big" matrices (>2Go) but it seems impossible
to allocate more than 2Go.

Example :

####################
octave-2.1.71:27> A=rand(400,400,800);
octave-2.1.71:28> sizeof(A)/10^9
ans = 1.0240
octave-2.1.71:29> clear all;
octave-2.1.71:30>  A=rand(400,800,800);
error: memory exhausted -- trying to return to prompt
###############

Is it possible to allocate more memory?




Any suggestions appreciated!

Regards,
