165    PetscErrorCode MatRegisterDynamic(const char *name,const char *path,const char *name_create,PetscErrorCode (*routine_create)(Mat))
166 
167    Not Collective
168 
169    Input Parameters:
170 +  name - name of a new user-defined matrix type
171 .  path - path (either absolute or relative) the library containing this solver
172 .  name_create - name of routine to create method context
173 -  routine_create - routine to create method context
174 
175    Notes:
176    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
177 
178    If dynamic libraries are used, then the fourth input argument (routine_create)
179    is ignored.
180 
181    Sample usage:
182 .vb
183    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
184                "MyMatCreate",MyMatCreate);
185 .ve
186 
187    Then, your solver can be chosen with the procedural interface via
188 $     MatSetType(Mat,"my_mat")
189    or at runtime via the option
190 $     -mat_type my_mat
191 
192    Level: advanced
193 
194    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
195          If your function is not being put into a shared library then use VecRegister() instead

1643 
1644    Not Collective
1645 
1646    Input Parameters:
1647 +  name_solver - name of a new user-defined compute-h module
1648 .  path - path (either absolute or relative) the library containing this solver
1649 .  name_create - name of routine to create method context
1650 -  routine_create - routine to create method context
1651 
1652    Level: developer
1653 
1654    Notes:
1655    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1656 
1657    If dynamic libraries are used, then the fourth input argument (routine_create)
1658    is ignored.
1659 
1660    Sample usage:
1661 .vb
1662    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1663                "MyHCreate",MyHCreate);
1664 .ve
1665 
1666    Then, your solver can be chosen with the procedural interface via
1667 $     MatMFFDSetType(mfctx,"my_h")
