156    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
157 
158    Not Collective
159 
160    Input Parameters:
161 +  name - name of a new user-defined matrix type
162 .  path - path (either absolute or relative) the library containing this solver
163 .  name_create - name of routine to create method context
164 -  routine_create - routine to create method context
165 
166    Notes:
167    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
168 
169    If dynamic libraries are used, then the fourth input argument (routine_create)
170    is ignored.
171 
172    Sample usage:
173 .vb
174    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
175                "MyMatCreate",MyMatCreate);
176 .ve
177 
178    Then, your solver can be chosen with the procedural interface via
179 $     MatSetType(Mat,"my_mat")
180    or at runtime via the option
181 $     -mat_type my_mat
182

184 
185    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
186          If your function is not being put into a shared library then use VecRegister() instead

1589 
1590    Not Collective
1591 
1592    Input Parameters:
1593 +  name_solver - name of a new user-defined compute-h module
1594 .  path - path (either absolute or relative) the library containing this solver
1595 .  name_create - name of routine to create method context
1596 -  routine_create - routine to create method context
1597 
1598    Level: developer
1599 
1600    Notes:
1601    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1602 
1603    If dynamic libraries are used, then the fourth input argument (routine_create)
1604    is ignored.
1605 
1606    Sample usage:
1607 .vb
1608    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1609                "MyHCreate",MyHCreate);
1610 .ve
1611 
1612    Then, your solver can be chosen with the procedural interface via
1613 $     MatMFFDSetType(mfctx,"my_h")
1614    or at runtime via the option
1615 $     -snes_mf_type my_h
