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

1339    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1340    matrix package.
1341 
1342    Synopsis:
1343    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1344 
1345    Not Collective
1346 
1347    Input Parameters:
1348 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1349 .  path - location of library where creation routine is
1350 .  name - name of function that creates the partitioning type, a string
1351 -  function - function pointer that creates the partitioning type
1352 
1353    Level: developer
1354 
1355    If dynamic libraries are used, then the fourth input argument (function)
1356    is ignored.
1357 
1358    Sample usage:
1359 .vb
1360    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1361                "MyPartCreate",MyPartCreate);
1362 .ve
1363 
1364    Then, your partitioner can be chosen with the procedural interface via
1365 $     MatPartitioningSetType(part,"my_part")
1366    or at runtime via the option
1367 $     -mat_partitioning_type my_part
1368 
1369    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1665 
1666    Not Collective
1667 
1668    Input Parameters:
1669 +  name_solver - name of a new user-defined compute-h module
1670 .  path - path (either absolute or relative) the library containing this solver
1671 .  name_create - name of routine to create method context
1672 -  routine_create - routine to create method context
1673 
1674    Level: developer
1675 
1676    Notes:
1677    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1678 
1679    If dynamic libraries are used, then the fourth input argument (routine_create)
1680    is ignored.
1681 
1682    Sample usage:
1683 .vb
1684    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1685                "MyHCreate",MyHCreate);
1686 .ve
1687 
1688    Then, your solver can be chosen with the procedural interface via
1689 $     MatMFFDSetType(mfctx,"my_h")
1690    or at runtime via the option
1691 $     -snes_mf_type my_h
