size too large for range of Octave's index type

[Tim Rueth]

I hit this problem a while back, and fixed it by changing my double-precision vars to single precision.  But now in my current sim, my ndgrid matrices are so large, even with single precision, that I'm getting the following error again:

 

error:  memory exhausted or requested size too large for range of Octave's index type

 

After getting this error, I did a "whos" and got:

 

421605065 elements using 1515209069 bytes

 

Okay, that's 1.41 GB.  What is Octave's limit?  In reading previous posts, it looks like Octave's limit is 2e9 elements or 2GB, but I'm not sure what build this refers to, in case later builds support more.  I'm running version 3.2.3 on Win7 w/6GB of RAM.  I also tried it on 3.2.4 and got the same error.

 

Thanks,
