167    MatRegisterDynamic - Adds a new matrix type

169    Synopsis:
170    PetscErrorCode MatRegisterDynamic(const char *name,const char *path,const char *name_create,PetscErrorCode (*routine_create)(Mat))
171 
172    Not Collective
173 
174    Input Parameters:
175 +  name - name of a new user-defined matrix type
176 .  path - path (either absolute or relative) the library containing this solver
177 .  name_create - name of routine to create method context
178 -  routine_create - routine to create method context
179 
180    Notes:
181    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
182 
183    If dynamic libraries are used, then the fourth input argument (routine_create)
184    is ignored.
185 
186    Sample usage:
187 .vb
188    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
189                "MyMatCreate",MyMatCreate);
190 .ve
191 
192    Then, your solver can be chosen with the procedural interface via
193 $     MatSetType(Mat,"my_mat")
194    or at runtime via the option
195 $     -mat_type my_mat
196 
197    Level: advanced
198 
199    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
200          If your function is not being put into a shared library then use VecRegister() instead

1661    PetscErrorCode MatMFFDRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatMFFD))
1662 
1663    Not Collective
1664 
1665    Input Parameters:
1666 +  name_solver - name of a new user-defined compute-h module
1667 .  path - path (either absolute or relative) the library containing this solver
1668 .  name_create - name of routine to create method context
1669 -  routine_create - routine to create method context
1670 
1671    Level: developer
1672 
1673    Notes:
1674    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1675 
1676    If dynamic libraries are used, then the fourth input argument (routine_create)
1677    is ignored.
1678 
1679    Sample usage:
1680 .vb
1681    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1682                "MyHCreate",MyHCreate);
1683 .ve
1684 
1685    Then, your solver can be chosen with the procedural interface via
1686 $     MatMFFDSetType(mfctx,"my_h")
1687    or at runtime via the option
1688 $     -snes_mf_type my_h
