Hi,

Looking at the PROJECTS I see that gmres is listed there as a missing function 
to be implemented.
As I had in Octave-Forge a version of the algorithm I had implemented some time 
ago with help from Jaroslav 
I changed it a bit to make its interface more matlab compatible and prepared a 
changeset against tip.

The changeset also adds the mgorth function that implements modified 
Gram-Schmidt orthogonalization, 
it was initially a private function but Jaroslav pointed out that it may be 
useful in its own right.

Could someone pleas check if this looks OK and maybe push it?
