[Trilinos-Users] node renumbering

[Riccardo Rossi]

Dear Micheal, Alan, list
   first of all i would like to thank you for your time. 

I have been looking at the Reindexing function you gave me,
unfortunately... honestly i don't have a clue of how to use it.
Just to start... i don't understand how shall i pass the matrix to be
reordered since the constructor only accepts the row_map.

i guess that my problem is already with the function transform. Is there
any place where i can find an example of use? i tried to look i the unit
tests but i could not find it...

changing subject i take the occasion to say that using the patch on
global assemble proposed by Alan last week i succesfully implemented my
parallel refinement algorithm (for triangular end tetra meshes).
...thanks once again for the help!!

Riccardo
