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

1341    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1342    matrix package.
1343 
1344    Synopsis:
1345    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1346 
1347    Not Collective
1348 
1349    Input Parameters:
1350 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1351 .  path - location of library where creation routine is
1352 .  name - name of function that creates the partitioning type, a string
1353 -  function - function pointer that creates the partitioning type
1354 
1355    Level: developer
1356 
1357    If dynamic libraries are used, then the fourth input argument (function)
1358    is ignored.
1359 
1360    Sample usage:
1361 .vb
1362    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1363                "MyPartCreate",MyPartCreate);
1364 .ve
1365 
1366    Then, your partitioner can be chosen with the procedural interface via
1367 $     MatPartitioningSetType(part,"my_part")
1368    or at runtime via the option
1369 $     -mat_partitioning_type my_part
1370 
1371    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1667 
1668    Not Collective
1669 
1670    Input Parameters:
1671 +  name_solver - name of a new user-defined compute-h module
1672 .  path - path (either absolute or relative) the library containing this solver
1673 .  name_create - name of routine to create method context
1674 -  routine_create - routine to create method context
1675 
1676    Level: developer
1677 
1678    Notes:
1679    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1680 
1681    If dynamic libraries are used, then the fourth input argument (routine_create)
1682    is ignored.
1683 
1684    Sample usage:
1685 .vb
1686    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1687                "MyHCreate",MyHCreate);
1688 .ve
1689 
1690    Then, your solver can be chosen with the procedural interface via
1691 $     MatMFFDSetType(mfctx,"my_h")
1692    or at runtime via the option
1693 $     -snes_mf_type my_h
