183    Synopsis:
184    PetscErrorCode MatRegisterDynamic(const char *name,const char *path,const char *name_create,PetscErrorCode (*routine_create)(Mat))
185 
186    Not Collective
187 
188    Input Parameters:
189 +  name - name of a new user-defined matrix type
190 .  path - path (either absolute or relative) the library containing this solver
191 .  name_create - name of routine to create method context
192 -  routine_create - routine to create method context
193 
194    Notes:
195    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
196 
197    If dynamic libraries are used, then the fourth input argument (routine_create)
198    is ignored.
199 
200    Sample usage:
201 .vb
202    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
203                "MyMatCreate",MyMatCreate);
204 .ve
205 
206    Then, your solver can be chosen with the procedural interface via
207 $     MatSetType(Mat,"my_mat")
208    or at runtime via the option
209 $     -mat_type my_mat

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

1720    Notes:
1721    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1722 
1723    If dynamic libraries are used, then the fourth input argument (routine_create)
1724    is ignored.
1725 
1726    Sample usage:
1727 .vb
1728    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1729                "MyHCreate",MyHCreate);
1730 .ve
1731 
1732    Then, your solver can be chosen with the procedural interface via
1733 $     MatMFFDSetType(mfctx,"my_h")
1734    or at runtime via the option
1735 $     -snes_mf_type my_h
