158 
159    Synopsis:
160    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
161 
162    Not Collective
163 
164    Input Parameters:
165 +  name - name of a new user-defined matrix type
166 .  path - path (either absolute or relative) the library containing this solver
167 .  name_create - name of routine to create method context
168 -  routine_create - routine to create method context
169 
170    Notes:
171    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
172 
173    If dynamic libraries are used, then the fourth input argument (routine_create)
174    is ignored.
175 
176    Sample usage:
177 .vb
178    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
179                "MyMatCreate",MyMatCreate);
180 .ve
181 
182    Then, your solver can be chosen with the procedural interface via
183 $     MatSetType(Mat,"my_mat")
184    or at runtime via the option
185 $     -mat_type my_mat

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

1606 
1607    Not Collective
1608 
1609    Input Parameters:
1610 +  name_solver - name of a new user-defined compute-h module
1611 .  path - path (either absolute or relative) the library containing this solver
1612 .  name_create - name of routine to create method context
1613 -  routine_create - routine to create method context
1614 
1615    Level: developer
1616 
1617    Notes:
1618    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1619 
1620    If dynamic libraries are used, then the fourth input argument (routine_create)
1621    is ignored.
1622 
1623    Sample usage:
1624 .vb
1625    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1626                "MyHCreate",MyHCreate);
1627 .ve
1628 
1629    Then, your solver can be chosen with the procedural interface via
1630 $     MatMFFDSetType(mfctx,"my_h")
1631    or at runtime via the option
1632 $     -snes_mf_type my_h
