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

1364    Then, your partitioner can be chosen with the procedural interface via
1365 $     MatPartitioningSetType(part,"my_part")
1366    or at runtime via the option
1367 $     -mat_partitioning_type my_part

1661    MatMFFDRegisterDynamic - Adds a method to the MatMFFD registry.
1662 
1663    Synopsis:
1664    PetscErrorCode MatMFFDRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatMFFD))
1665 
1666    Not Collective
1667 
1668    Input Parameters:
1669 +  name_solver - name of a new user-defined compute-h module
1670 .  path - path (either absolute or relative) the library containing this solver
1671 .  name_create - name of routine to create method context
1672 -  routine_create - routine to create method context
1673 
1674    Level: developer
1675 
1676    Notes:
1677    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1678 
1679    If dynamic libraries are used, then the fourth input argument (routine_create)
1680    is ignored.
1681 
1682    Sample usage:
1683 .vb
1684    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1685                "MyHCreate",MyHCreate);
1686 .ve
1687 
1688    Then, your solver can be chosen with the procedural interface via
1689 $     MatMFFDSetType(mfctx,"my_h")
1690    or at runtime via the option
1691 $     -snes_mf_type my_h
