170    PetscErrorCode MatRegisterDynamic(const char *name,const char *path,const char *name_create,PetscErrorCode (*routine_create)(Mat))
171 
172    Not Collective
173 
174    Input Parameters:
175 +  name - name of a new user-defined matrix type
176 .  path - path (either absolute or relative) the library containing this solver
177 .  name_create - name of routine to create method context
178 -  routine_create - routine to create method context
179 
180    Notes:
181    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
182 
183    If dynamic libraries are used, then the fourth input argument (routine_create)
184    is ignored.
185 
186    Sample usage:
187 .vb
188    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
189                "MyMatCreate",MyMatCreate);
190 .ve
191 
192    Then, your solver can be chosen with the procedural interface via
193 $     MatSetType(Mat,"my_mat")
194    or at runtime via the option
195 $     -mat_type my_mat
196 
197    Level: advanced
198 
199    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
200          If your function is not being put into a shared library then use VecRegister() instead

1344 .  path - location of library where creation routine is
1345 .  name - name of function that creates the partitioning type, a string
1346 -  function - function pointer that creates the partitioning type
1347 
1348    Level: developer
1349 
1350    If dynamic libraries are used, then the fourth input argument (function)
1351    is ignored.
1352 
1353    Sample usage:
1354 .vb
1355    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1356                "MyPartCreate",MyPartCreate);
1357 .ve
1358 
1359    Then, your partitioner can be chosen with the procedural interface via
1360 $     MatPartitioningSetType(part,"my_part")
1361    or at runtime via the option
1362 $     -mat_partitioning_type my_part
1363 
1364    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1656    MatMFFDRegisterDynamic - Adds a method to the MatMFFD registry.

1658    Synopsis:
1659    PetscErrorCode MatMFFDRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatMFFD))
1660 
1661    Not Collective
1662 
1663    Input Parameters:
1664 +  name_solver - name of a new user-defined compute-h module
1665 .  path - path (either absolute or relative) the library containing this solver
1666 .  name_create - name of routine to create method context
1667 -  routine_create - routine to create method context
1668 
1669    Level: developer
1670 
1671    Notes:
1672    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1673 
1674    If dynamic libraries are used, then the fourth input argument (routine_create)
1675    is ignored.
1676 
1677    Sample usage:
1678 .vb
1679    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1680                "MyHCreate",MyHCreate);
1681 .ve
1682 
1683    Then, your solver can be chosen with the procedural interface via
1684 $     MatMFFDSetType(mfctx,"my_h")
1685    or at runtime via the option
1686 $     -snes_mf_type my_h
