The reason why fortran indexing is used is that the principal external 
library that octave links to is LAPACK that is itself written in 
fortran. The function Array<T>::fortran_vec() returns a point of typt T* 
to the data as it is stored in memory by octave that uses the fortran 
storage convention....

True for C++, but I don't see that the conventions of the scripting 
language impose any formality on the storage of the data within octave 
itself....
