MatIJSetEdgesIS

 sets the edges in the pseudograph matrix. The edges are specified as two index sets of vertices of equal length: outgoing and incoming vertices (ix -> iy).

Synopsis

#undef  __FUNCT__
#define __FUNCT__ "MatIJSetEdgesIS"
PetscErrorCode MatIJSetEdgesIS(Mat A, IS ix, IS iy)
Not collective

Input parameters

A - pseudograph
ix - list of outgoing vertices
iy - list of incoming vertices

Note

This will cause the matrix to be be put in an unassembled state.- . Edges are assembled during MatAssembly -- moved to the processor owning the outgoing vertex.
Communicators of the IS objects must match that of MatIJ. -
