158    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
159 
160    Not Collective
161 
162    Input Parameters:
163 +  name - name of a new user-defined matrix type
164 .  path - path (either absolute or relative) the library containing this solver
165 .  name_create - name of routine to create method context
166 -  routine_create - routine to create method context
167 
168    Notes:
169    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
170 
171    If dynamic libraries are used, then the fourth input argument (routine_create)
172    is ignored.
173 
174    Sample usage:
175 .vb
176    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
177                "MyMatCreate",MyMatCreate);
178 .ve
179 
180    Then, your solver can be chosen with the procedural interface via
181 $     MatSetType(Mat,"my_mat")
182    or at runtime via the option
183 $     -mat_type my_mat
184

186 
187    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
188          If your function is not being put into a shared library then use VecRegister() instead

1599 
1600    Not Collective
1601 
1602    Input Parameters:
1603 +  name_solver - name of a new user-defined compute-h module
1604 .  path - path (either absolute or relative) the library containing this solver
1605 .  name_create - name of routine to create method context
1606 -  routine_create - routine to create method context
1607 
1608    Level: developer
1609 
1610    Notes:
1611    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1612 
1613    If dynamic libraries are used, then the fourth input argument (routine_create)
1614    is ignored.
1615 
1616    Sample usage:
1617 .vb
1618    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1619                "MyHCreate",MyHCreate);
1620 .ve
1621 
1622    Then, your solver can be chosen with the procedural interface via
1623 $     MatMFFDSetType(mfctx,"my_h")
1624    or at runtime via the option
1625 $     -snes_mf_type my_h
