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

1353    MatPartitioningRegisterDynamic - Adds a new sparse matrix partitioning to the
1354    matrix package.
1355 
1356    Synopsis:
1357    PetscErrorCode MatPartitioningRegisterDynamic(const char *name_partitioning,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatPartitioning))
1358 
1359    Not Collective
1360 
1361    Input Parameters:
1362 +  sname - name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
1363 .  path - location of library where creation routine is
1364 .  name - name of function that creates the partitioning type, a string
1365 -  function - function pointer that creates the partitioning type
1366 
1367    Level: developer
1368 
1369    If dynamic libraries are used, then the fourth input argument (function)
1370    is ignored.
1371 
1372    Sample usage:
1373 .vb
1374    MatPartitioningRegisterDynamic("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
1375                "MyPartCreate",MyPartCreate);
1376 .ve
1377 
1378    Then, your partitioner can be chosen with the procedural interface via
1379 $     MatPartitioningSetType(part,"my_part")
1380    or at runtime via the option
1381 $     -mat_partitioning_type my_part
1382 
1383    $PETSC_ARCH occuring in pathname will be replaced with appropriate values.

1679 
1680    Not Collective
1681 
1682    Input Parameters:
1683 +  name_solver - name of a new user-defined compute-h module
1684 .  path - path (either absolute or relative) the library containing this solver
1685 .  name_create - name of routine to create method context
1686 -  routine_create - routine to create method context
1687 
1688    Level: developer
1689 
1690    Notes:
1691    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1692 
1693    If dynamic libraries are used, then the fourth input argument (routine_create)
1694    is ignored.
1695 
1696    Sample usage:
1697 .vb
1698    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1699                "MyHCreate",MyHCreate);
1700 .ve
1701 
1702    Then, your solver can be chosen with the procedural interface via
1703 $     MatMFFDSetType(mfctx,"my_h")
1704    or at runtime via the option
1705 $     -snes_mf_type my_h
