Well. It looks like you just requested Octave to allocate about 420
megabytes of memory. That fits in my machine, where I have 4 gigs and
lots of leg room, but maybe not on yours.

One fix may be to not allocate that much memory. If you have a
for-loop, as I imagine you are, you may find it better to transform it
into an equivalent while loop. As I understand it, for 1 = 1:55*10^6
actually creates a vector of that size.

On the other hand, if you actually are using a vector of 420 megabytes
for vectorisation routines, I think the only fix is to get a computer
with more memory.
