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

1586 
1587    Not Collective
1588 
1589    Input Parameters:
1590 +  name_solver - name of a new user-defined compute-h module
1591 .  path - path (either absolute or relative) the library containing this solver
1592 .  name_create - name of routine to create method context
1593 -  routine_create - routine to create method context
1594 
1595    Level: developer
1596 
1597    Notes:
1598    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1599 
1600    If dynamic libraries are used, then the fourth input argument (routine_create)
1601    is ignored.
1602 
1603    Sample usage:
1604 .vb
1605    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1606                "MyHCreate",MyHCreate);
1607 .ve
1608 
1609    Then, your solver can be chosen with the procedural interface via
1610 $     MatMFFDSetType(mfctx,"my_h")
1611    or at runtime via the option
1612 $     -snes_mf_type my_h
