166    MatRegisterDynamic - Adds a new matrix type

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

1657    MatMFFDRegisterDynamic - Adds a method to the MatMFFD registry.
1658 
1659    Synopsis:
1660    PetscErrorCode MatMFFDRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(MatMFFD))
1661 
1662    Not Collective
1663 
1664    Input Parameters:
1665 +  name_solver - name of a new user-defined compute-h module
1666 .  path - path (either absolute or relative) the library containing this solver
1667 .  name_create - name of routine to create method context
1668 -  routine_create - routine to create method context
1669 
1670    Level: developer
1671 
1672    Notes:
1673    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1674 
1675    If dynamic libraries are used, then the fourth input argument (routine_create)
1676    is ignored.
1677 
1678    Sample usage:
1679 .vb
1680    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1681                "MyHCreate",MyHCreate);
1682 .ve
1683 
1684    Then, your solver can be chosen with the procedural interface via
1685 $     MatMFFDSetType(mfctx,"my_h")
1686    or at runtime via the option
1687 $     -snes_mf_type my_h
