Memory exaustion or size too large for index

[Carnë Draug]

Hi

I'm having some problems memory. I get this error when running my program

error: memory exhausted or requested size too large for range of
Octave's index type -- trying to return to prompt

Sure, I'm dealing with a matrix of size 300*350*1*2500 (uint8) and
making a bunch of stuff to it. What are the limits and how can I
increase it? I know I have enough memory (I have a total of almost 9Gb
although 7 are swap) and my kernel should not be limiting the
available memory to octave (ulimit -m gives me unlimited). If I need
to compile it from source, what options should I change to get over
this?

Thanks in advance,
Carnë

PS: I don't think it may be necessary but here's the part of the
program that I think is giving me the problem (

reaches line 8.
