Vector with >2^32 elements in 64 bit octave

[Johan Lans]

Hi

 I want to make a calculation with a vector larger than 2^32 elements. To be able to do this I've gotten access to a 64bit computer with a lot of RAM, and installed octave 3.0.1. However, when I do 

octave:27> n = [1:2^31];

I get:

error: invalid range

error: evaluating assignment _expression_ near line 27, column 3

Why is this? I have "Octave was configured for "x86_64-pc-linux-gnu".", and there is no problem doing x=int64(2^40), for example. I'm not sure if I can install a newer version of octave, since I don't have root access.
