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

[japindado]

This topic has been discussed before, but I have read all of the threads and
none of them have the answer to my issue, so I am posting here hoping
someone can help...  Basically, Octave will not allow the total memory
consumed by all variables to exceed ~1.5GB...  My machine runs Windows7
Enterprise N 64-bit on an Intel i7 with 9GB RAM. Any help would be greatly
appreciated.

Here is my output/code:
