Memory exhausted

[J Stasko]

I am running fsolve on matrix with 47089 elements.  I get the following error,

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

This is even after executing the called function, the error is somewhere in fsolve(@whatever,matrix) after @whatever returns.

When I call fsolve with 40000 elements, I don't get the error.  I'm guessing, maybe, that there's some option I can use to change this.  I'm going to try to offer the jacobian to this fsolve, but I don't know if that will help.

Thanks,
