168    MatRegisterDynamic - Adds a new matrix type

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

1349    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1350    matrix package.
1351 
1352    Synopsis:
1353    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1354 
1355    Not Collective
1356 
1357    Input Parameters:
1358 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1359 .  path - location of library where creation routine is
1360 .  name - name of function that creates the partitioning type, a string
1361 -  function - function pointer that creates the partitioning type
1362 
1363    Level: developer
1364 
1365    If dynamic libraries are used, then the fourth input argument (function)
1366    is ignored.
1367 
1368    Sample usage:
1369 .vb
1370    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1371                "MyPartCreate",MyPartCreate);
1372 .ve
1373 
1374    Then, your partitioner can be chosen with the procedural interface via
1375 $     MatPartitioningSetType(part,"my_part")
1376    or at runtime via the option
1377 $     -mat_partitioning_type my_part
1378 
1379    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1675 
1676    Not Collective
1677 
1678    Input Parameters:
1679 +  name_solver - name of a new user-defined compute-h module
1680 .  path - path (either absolute or relative) the library containing this solver
1681 .  name_create - name of routine to create method context
1682 -  routine_create - routine to create method context
1683 
1684    Level: developer
1685 
1686    Notes:
1687    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1688 
1689    If dynamic libraries are used, then the fourth input argument (routine_create)
1690    is ignored.
1691 
1692    Sample usage:
1693 .vb
1694    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1695                "MyHCreate",MyHCreate);
1696 .ve
1697 
1698    Then, your solver can be chosen with the procedural interface via
1699 $     MatMFFDSetType(mfctx,"my_h")
1700    or at runtime via the option
1701 $     -snes_mf_type my_h
