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

1337    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1338    matrix package.
1339 
1340    Synopsis:
1341    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1342 
1343    Not Collective
1344 
1345    Input Parameters:
1346 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1347 .  path - location of library where creation routine is
1348 .  name - name of function that creates the partitioning type, a string
1349 -  function - function pointer that creates the partitioning type
1350 
1351    Level: developer
1352 
1353    If dynamic libraries are used, then the fourth input argument (function)
1354    is ignored.
1355 
1356    Sample usage:
1357 .vb
1358    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1359                "MyPartCreate",MyPartCreate);
1360 .ve
1361 
1362    Then, your partitioner can be chosen with the procedural interface via
1363 $     MatPartitioningSetType(part,"my_part")
1364    or at runtime via the option
1365 $     -mat_partitioning_type my_part
1366 
1367    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1663 
1664    Not Collective
1665 
1666    Input Parameters:
1667 +  name_solver - name of a new user-defined compute-h module
1668 .  path - path (either absolute or relative) the library containing this solver
1669 .  name_create - name of routine to create method context
1670 -  routine_create - routine to create method context
1671 
1672    Level: developer
1673 
1674    Notes:
1675    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1676 
1677    If dynamic libraries are used, then the fourth input argument (routine_create)
1678    is ignored.
1679 
1680    Sample usage:
1681 .vb
1682    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1683                "MyHCreate",MyHCreate);
1684 .ve
1685 
1686    Then, your solver can be chosen with the procedural interface via
1687 $     MatMFFDSetType(mfctx,"my_h")
1688    or at runtime via the option
1689 $     -snes_mf_type my_h
