Loading a 318 MB matrix into Octave 32 bit

[Elliot Gorokhovsky]

I am running 32 bit octave on a 64 bit system (I would really like to keep it that way if possible) and I have a .mat with a double matrix size 5492743 by 3. Octave says it takes 131,825,832 bytes. When I run the following script (with num=140000) I get, immediately[, error: memory exhausted or requested size too large for range of Octave's index type -- trying to return to prompt.

data = "">

for i = 1:length(data)-num

data(i,:)=[data(i,1:3),vec(data((i+1):(i+num),1:3)')'];

disp(i)

end

data = "">

Can I fix this without recompiling? If I have to recompile, how do I do it?

Thanks,
