168    MatRegisterDynamic - Adds a new matrix type

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

1344    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1345    matrix package.
1346 
1347    Synopsis:
1348    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1349 
1350    Not Collective
1351 
1352    Input Parameters:
1353 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1354 .  path - location of library where creation routine is
1355 .  name - name of function that creates the partitioning type, a string
1356 -  function - function pointer that creates the partitioning type
1357 
1358    Level: developer
1359 
1360    If dynamic libraries are used, then the fourth input argument (function)
1361    is ignored.
1362 
1363    Sample usage:
1364 .vb
1365    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1366                "MyPartCreate",MyPartCreate);
1367 .ve
1368 
1369    Then, your partitioner can be chosen with the procedural interface via
1370 $     MatPartitioningSetType(part,"my_part")
1371    or at runtime via the option
1372 $     -mat_partitioning_type my_part
1373 
1374    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1670 
1671    Not Collective
1672 
1673    Input Parameters:
1674 +  name_solver - name of a new user-defined compute-h module
1675 .  path - path (either absolute or relative) the library containing this solver
1676 .  name_create - name of routine to create method context
1677 -  routine_create - routine to create method context
1678 
1679    Level: developer
1680 
1681    Notes:
1682    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1683 
1684    If dynamic libraries are used, then the fourth input argument (routine_create)
1685    is ignored.
1686 
1687    Sample usage:
1688 .vb
1689    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1690                "MyHCreate",MyHCreate);
1691 .ve
1692 
1693    Then, your solver can be chosen with the procedural interface via
1694 $     MatMFFDSetType(mfctx,"my_h")
1695    or at runtime via the option
1696 $     -snes_mf_type my_h
