I haven't got around to figuring out a good answer to the following question.
I am glad if someone could help me.
Given a *:MPI::Vector, what is the best way to assign element wise reciprocal
value?
Something like
for (i in the set of locally owned elements of the vector)
v(i) = 1./v(i);
should work. I believe that all of the MPI vector types have a way to get an
IndexSet object that describes which elements they own.
Of course, to write into a vector, it cannot store ghost elements.
