150 
151    Synopsis:
152    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
153 
154    Not Collective
155 
156    Input Parameters:
157 +  name - name of a new user-defined matrix type
158 .  path - path (either absolute or relative) the library containing this solver
159 .  name_create - name of routine to create method context
160 -  routine_create - routine to create method context
161 
162    Notes:
163    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
164 
165    If dynamic libraries are used, then the fourth input argument (routine_create)
166    is ignored.
167 
168    Sample usage:
169 .vb
170    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
171                "MyMatCreate",MyMatCreate);
172 .ve
173 
174    Then, your solver can be chosen with the procedural interface via
175 $     MatSetType(Mat,"my_mat")
176    or at runtime via the option
177 $     -mat_type my_mat
178 
179    Level: advanced
180 
181    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
182          If your function is not being put into a shared library then use VecRegister() instead

1583 
1584    Not Collective
1585 
1586    Input Parameters:
1587 +  name_solver - name of a new user-defined compute-h module
1588 .  path - path (either absolute or relative) the library containing this solver
1589 .  name_create - name of routine to create method context
1590 -  routine_create - routine to create method context
1591 
1592    Level: developer
1593 
1594    Notes:
1595    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1596 
1597    If dynamic libraries are used, then the fourth input argument (routine_create)
1598    is ignored.
1599 
1600    Sample usage:
1601 .vb
1602    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1603                "MyHCreate",MyHCreate);
1604 .ve
1605 
1606    Then, your solver can be chosen with the procedural interface via
1607 $     MatMFFDSetType(mfctx,"my_h")
1608    or at runtime via the option
1609 $     -snes_mf_type my_h
