169    MatRegisterDynamic - Adds a new matrix type

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

1357    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1358    matrix package.
1359 
1360    Synopsis:
1361    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1362 
1363    Not Collective
1364 
1365    Input Parameters:
1366 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1367 .  path - location of library where creation routine is
1368 .  name - name of function that creates the partitioning type, a string
1369 -  function - function pointer that creates the partitioning type
1370 
1371    Level: developer
1372 
1373    If dynamic libraries are used, then the fourth input argument (function)
1374    is ignored.
1375 
1376    Sample usage:
1377 .vb
1378    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1379                "MyPartCreate",MyPartCreate);
1380 .ve
1381 
1382    Then, your partitioner can be chosen with the procedural interface via
1383 $     MatPartitioningSetType(part,"my_part")
1384    or at runtime via the option
1385 $     -mat_partitioning_type my_part
1386 
1387    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1686 
1687    Not Collective
1688 
1689    Input Parameters:
1690 +  name_solver - name of a new user-defined compute-h module
1691 .  path - path (either absolute or relative) the library containing this solver
1692 .  name_create - name of routine to create method context
1693 -  routine_create - routine to create method context
1694 
1695    Level: developer
1696 
1697    Notes:
1698    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1699 
1700    If dynamic libraries are used, then the fourth input argument (routine_create)
1701    is ignored.
1702 
1703    Sample usage:
1704 .vb
1705    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1706                "MyHCreate",MyHCreate);
1707 .ve
1708 
1709    Then, your solver can be chosen with the procedural interface via
1710 $     MatMFFDSetType(mfctx,"my_h")
1711    or at runtime via the option
1712 $     -snes_mf_type my_h
