pinv() error message

[Ether Jones]

Please, what settings do I need to change
so Octave can complete the following computation
without error. I have 3GB installed memory,

and Process Explorer says I have over 2GB

of physical memory available:

+ size (A)
   25362    3331

+ size (b)
   25362    1

+ X = pinv(A) * b;

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