161    Synopsis:
162    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
163 
164    Not Collective
165 
166    Input Parameters:
167 +  name - name of a new user-defined matrix type
168 .  path - path (either absolute or relative) the library containing this solver
169 .  name_create - name of routine to create method context
170 -  routine_create - routine to create method context
171 
172    Notes:
173    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
174 
175    If dynamic libraries are used, then the fourth input argument (routine_create)
176    is ignored.
177 
178    Sample usage:
179 .vb
180    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
181                "MyMatCreate",MyMatCreate);
182 .ve
183 
184    Then, your solver can be chosen with the procedural interface via
185 $     MatSetType(Mat,"my_mat")
186    or at runtime via the option
187 $     -mat_type my_mat
188 
189    Level: advanced
190 
191    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
192          If your function is not being put into a shared library then use VecRegister() instead

1612 
1613    Not Collective
1614 
1615    Input Parameters:
1616 +  name_solver - name of a new user-defined compute-h module
1617 .  path - path (either absolute or relative) the library containing this solver
1618 .  name_create - name of routine to create method context
1619 -  routine_create - routine to create method context
1620 
1621    Level: developer
1622 
1623    Notes:
1624    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1625 
1626    If dynamic libraries are used, then the fourth input argument (routine_create)
1627    is ignored.
1628 
1629    Sample usage:
1630 .vb
1631    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1632                "MyHCreate",MyHCreate);
1633 .ve
1634 
1635    Then, your solver can be chosen with the procedural interface via
1636 $     MatMFFDSetType(mfctx,"my_h")
1637    or at runtime via the option
1638 $     -snes_mf_type my_h
