out of memory or dimension too large for Octave's index type

[dkeck]

I am using glpk to solve an optimization problem of the form 'Ax<=b'.
A submatrix of 'A' with size 5280 x 4608 fails to be built with "out of
memory or dimension too large for Octave's index type"-error. These are
24,330,240 elements which are far below the 2e9 element border
(http://octave.1599824.n4.nabble.com/error-memory-exhausted-or-requested-size-too-large-for-range-of-Octave-s-index-type-td3357172.html).

The complete size of A will be 7398 x 4608 in the current scenario. And
should also work fine:

But I could not test it yet.

Does anybody have an idea what could cause the "out of memory"-error here?

Regards,
Daniel
