148    MatRegisterDynamic - Adds a new matrix type
149 
150    Synopsis:
151    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
152 
153    Not Collective
154 
155    Input Parameters:
156 +  name - name of a new user-defined matrix type
157 .  path - path (either absolute or relative) the library containing this solver
158 .  name_create - name of routine to create method context
159 -  routine_create - routine to create method context
160 
161    Notes:
162    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
163 
164    If dynamic libraries are used, then the fourth input argument (routine_create)
165    is ignored.
166 
167    Sample usage:
168 .vb
169    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
170                "MyMatCreate",MyMatCreate);
171 .ve
172 
173    Then, your solver can be chosen with the procedural interface via
174 $     MatSetType(Mat,"my_mat")
175    or at runtime via the option
176 $     -mat_type my_mat
177 
178    Level: advanced
179 
180    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
181          If your function is not being put into a shared library then use VecRegister() instead

1582 
1583    Not Collective
1584 
1585    Input Parameters:
1586 +  name_solver - name of a new user-defined compute-h module
1587 .  path - path (either absolute or relative) the library containing this solver
1588 .  name_create - name of routine to create method context
1589 -  routine_create - routine to create method context
1590 
1591    Level: developer
1592 
1593    Notes:
1594    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1595 
1596    If dynamic libraries are used, then the fourth input argument (routine_create)
1597    is ignored.
1598 
1599    Sample usage:
1600 .vb
1601    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1602                "MyHCreate",MyHCreate);
1603 .ve
1604 
1605    Then, your solver can be chosen with the procedural interface via
1606 $     MatMFFDSetType(mfctx,"my_h")
1607    or at runtime via the option
1608 $     -snes_mf_type my_h
