Ok, so I lied it will introduce another user visible change. The interface to colamd and symamd changed, in that the definition of the second argument to colamd and symamd changed. This is used when determining which rows/cols are to be considered as dense and moved to the end of the reordering.David, This sounds like good news. That new code, especially with 64 bit versions will be a nice advantage to octave. While I agree that moving to a new package is a little bit of pain. It will be nice to have all the sparse routines in one package. Have you yet had time to figure out wither this will change any of the Sparse class in octave. ie. will those of us who write sparse code need to plan for any changes?
I checked in an updated version of Fcolamd, Fsymand and Fetree that can be built for 64-bit systems. Check the help of colamd and symamd for the new definition of "knobs"...
Cheers David
