185    Synopsis:
186    PetscErrorCode MatRegisterDynamic(const char *name,const char *path,const char *name_create,PetscErrorCode (*routine_create)(Mat))
187 
188    Not Collective
189 
190    Input Parameters:
191 +  name - name of a new user-defined matrix type
192 .  path - path (either absolute or relative) the library containing this solver
193 .  name_create - name of routine to create method context
194 -  routine_create - routine to create method context
195 
196    Notes:
197    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
198 
199    If dynamic libraries are used, then the fourth input argument (routine_create)
200    is ignored.
201 
202    Sample usage:
203 .vb
204    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
205                "MyMatCreate",MyMatCreate);
206 .ve
207 
208    Then, your solver can be chosen with the procedural interface via
209 $     MatSetType(Mat,"my_mat")
210    or at runtime via the option
211 $     -mat_type my_mat
212 
213    Level: advanced
214 
215    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
216          If your function is not being put into a shared library then use VecRegister() instead

1721 
1722    Not Collective
1723 
1724    Input Parameters:
1725 +  name_solver - name of a new user-defined compute-h module
1726 .  path - path (either absolute or relative) the library containing this solver
1727 .  name_create - name of routine to create method context
1728 -  routine_create - routine to create method context
1729 
1730    Level: developer
1731 
1732    Notes:
1733    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1734 
1735    If dynamic libraries are used, then the fourth input argument (routine_create)
1736    is ignored.
1737 
1738    Sample usage:
1739 .vb
1740    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1741                "MyHCreate",MyHCreate);
1742 .ve
1743 
1744    Then, your solver can be chosen with the procedural interface via
1745 $     MatMFFDSetType(mfctx,"my_h")
1746    or at runtime via the option
