MatOrderingRegisterDynamic

 Adds a new sparse matrix ordering to the matrix package.

Synopsis

PetscErrorCode MatOrderingRegisterDynamic(const char *name_ordering,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatOrdering))
Not Collective

Input Parameters

sname - name of ordering (for example MATORDERINGND)
path - location of library where creation routine is
name - name of function that creates the ordering type,a string
function - function pointer that creates the ordering

If dynamic libraries are used, then the fourth input argument (function) is ignored.

Sample usage

   MatOrderingRegisterDynamic("my_order",/home/username/my_lib/lib/libO/solaris/mylib.a,
               "MyOrder",MyOrder);

Then, your partitioner can be chosen with the procedural interface via 

    MatOrderingSetType(part,"my_order)
or at runtime via the option 
    -pc_factor_mat_ordering_type my_order

${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
