[petsc-users] question about extracting numbers from a matrix

[Michael Povolotskyi]

Hello everybody,
I have a sparse matrix defined on 1 MPI process.
I want to extract all entries from it (including zeros) and put them 
into an array to use as an argument for some lapack functions.
What is the most optimal way of doing this?
Thank you,
Michael.
