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

1638 
1639    Not Collective
1640 
1641    Input Parameters:
1642 +  name_solver - name of a new user-defined compute-h module
1643 .  path - path (either absolute or relative) the library containing this solver
1644 .  name_create - name of routine to create method context
1645 -  routine_create - routine to create method context
1646 
1647    Level: developer
1648 
1649    Notes:
1650    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1651 
1652    If dynamic libraries are used, then the fourth input argument (routine_create)
1653    is ignored.
1654 
1655    Sample usage:
1656 .vb
1657    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1658                "MyHCreate",MyHCreate);
1659 .ve
1660 
1661    Then, your solver can be chosen with the procedural interface via
1662 $     MatMFFDSetType(mfctx,"my_h")
