Creates matrix compatiable with two distributed arrays

#include "petscdmadda.h" 
PetscErrorCode  DMADDAGetMatrixNS(DM dm, DM dmc, const MatType mtype, Mat *mat)

Collective on ADDA

addar -the distributed array for which we create the matrix, which indexes the rows

addac -the distributed array for which we create the matrix, which indexes the columns

mtype -Supported types are MATSEQAIJ, MATMPIAIJ, MATSEQBAIJ, MATMPIBAIJ, or any type which inherits from one of these (such as MATAIJ, MATLUSOL, etc.).

mat -the empty Jacobian

distributed array, matrix
