Dear Jed, I am taking a look at ex15 ( http://www.mcs.anl.gov/petsc/petsc-current/src/mat/examples/tutorials/ex15.c.html ). I am very confused with this. In Section 3.5 Partitioning of the manual, one special Mat, that is 'adj', need to be established. However, in ex15, the common matrix is created. Does the matrix automatically contain the connection information?
