158    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
159 
160    Not Collective
161 
162    Input Parameters:
163 +  name - name of a new user-defined matrix type
164 .  path - path (either absolute or relative) the library containing this solver
165 .  name_create - name of routine to create method context
166 -  routine_create - routine to create method context
167 
168    Notes:
169    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
170 
171    If dynamic libraries are used, then the fourth input argument (routine_create)
172    is ignored.
173 
174    Sample usage:
175 .vb
176    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
177                "MyMatCreate",MyMatCreate);
178 .ve
179 
180    Then, your solver can be chosen with the procedural interface via
181 $     MatSetType(Mat,"my_mat")
182    or at runtime via the option
183 $     -mat_type my_mat

186 
187    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
188          If your function is not being put into a shared library then use VecRegister() instead

1596 
1597    Not Collective
1598 
1599    Input Parameters:
1600 +  name_solver - name of a new user-defined compute-h module
1601 .  path - path (either absolute or relative) the library containing this solver
1602 .  name_create - name of routine to create method context
1603 -  routine_create - routine to create method context
1604 
1605    Level: developer
1606 
1607    Notes:
1608    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1609 
1610    If dynamic libraries are used, then the fourth input argument (routine_create)
1611    is ignored.
1612 
1613    Sample usage:
1614 .vb
1615    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1616                "MyHCreate",MyHCreate);
1617 .ve
1618 
1619    Then, your solver can be chosen with the procedural interface via
1620 $     MatMFFDSetType(mfctx,"my_h")
1621    or at runtime via the option
1622 $     -snes_mf_type my_h
