167    MatRegisterDynamic - Adds a new matrix type

169    Synopsis:
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

1340    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1341    matrix package.
1342 
1343    Synopsis:
1344    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1345 
1346    Not Collective
1347 
1348    Input Parameters:
1349 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1350 .  path - location of library where creation routine is
1351 .  name - name of function that creates the partitioning type, a string
1352 -  function - function pointer that creates the partitioning type
1353 
1354    Level: developer
1355 
1356    If dynamic libraries are used, then the fourth input argument (function)
1357    is ignored.
1358 
1359    Sample usage:
1360 .vb
1361    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1362                "MyPartCreate",MyPartCreate);
1363 .ve
1364 
1365    Then, your partitioner can be chosen with the procedural interface via
1366 $     MatPartitioningSetType(part,"my_part")
1367    or at runtime via the option
1368 $     -mat_partitioning_type my_part
1369 
1370    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1666 
1667    Not Collective
1668 
1669    Input Parameters:
1670 +  name_solver - name of a new user-defined compute-h module
1671 .  path - path (either absolute or relative) the library containing this solver
1672 .  name_create - name of routine to create method context
1673 -  routine_create - routine to create method context
1674 
1675    Level: developer
1676 
1677    Notes:
1678    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1679 
1680    If dynamic libraries are used, then the fourth input argument (routine_create)
1681    is ignored.
1682 
1683    Sample usage:
1684 .vb
1685    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1686                "MyHCreate",MyHCreate);
1687 .ve
1688 
1689    Then, your solver can be chosen with the procedural interface via
1690 $     MatMFFDSetType(mfctx,"my_h")
1691    or at runtime via the option
1692 $     -snes_mf_type my_h
