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

1356    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1357    matrix package.
1358 
1359    Synopsis:
1360    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1361 
1362    Not Collective
1363 
1364    Input Parameters:
1365 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1366 .  path - location of library where creation routine is
1367 .  name - name of function that creates the partitioning type, a string
1368 -  function - function pointer that creates the partitioning type
1369 
1370    Level: developer
1371 
1372    If dynamic libraries are used, then the fourth input argument (function)
1373    is ignored.
1374 
1375    Sample usage:
1376 .vb
1377    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1378                "MyPartCreate",MyPartCreate);
1379 .ve
1380 
1381    Then, your partitioner can be chosen with the procedural interface via
1382 $     MatPartitioningSetType(part,"my_part")
1383    or at runtime via the option
1384 $     -mat_partitioning_type my_part
1385 
1386    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1683 
1684    Not Collective
1685 
1686    Input Parameters:
1687 +  name_solver - name of a new user-defined compute-h module
1688 .  path - path (either absolute or relative) the library containing this solver
1689 .  name_create - name of routine to create method context
1690 -  routine_create - routine to create method context
1691 
1692    Level: developer
1693 
1694    Notes:
1695    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1696 
1697    If dynamic libraries are used, then the fourth input argument (routine_create)
1698    is ignored.
1699 
1700    Sample usage:
1701 .vb
1702    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1703                "MyHCreate",MyHCreate);
1704 .ve
1705 
1706    Then, your solver can be chosen with the procedural interface via
1707 $     MatMFFDSetType(mfctx,"my_h")
1708    or at runtime via the option
1709 $     -snes_mf_type my_h
