# MatOrderingRegisterDynamic

Adds a new sparse matrix ordering to the matrix package.

### Synopsis

    PetscErrorCode MatOrderingRegisterDynamic(char *name_ordering,char *path,char *name_create,PetscErrorCode (*routine_create)(MatOrdering))

Not Collective

### Input Parameters

| sname | - name of ordering (for example MATORDERING_ND)
| 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.
