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

1666 
1667    Input Parameters:
1668 +  name_solver - name of a new user-defined compute-h module
1669 .  path - path (either absolute or relative) the library containing this solver
1670 .  name_create - name of routine to create method context
1671 -  routine_create - routine to create method context
1672 
1673    Level: developer
1674 
1675    Notes:
1676    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1677 
1678    If dynamic libraries are used, then the fourth input argument (routine_create)
1679    is ignored.
1680 
1681    Sample usage:
1682 .vb
1683    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1684                "MyHCreate",MyHCreate);
1685 .ve
1686 
1687    Then, your solver can be chosen with the procedural interface via
1688 $     MatMFFDSetType(mfctx,"my_h")
1689    or at runtime via the option
1690 $     -snes_mf_type my_h
