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

183 
184    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
185          If your function is not being put into a shared library then use VecRegister() instead

1590 
1591    Not Collective
1592 
1593    Input Parameters:
1594 +  name_solver - name of a new user-defined compute-h module
1595 .  path - path (either absolute or relative) the library containing this solver
1596 .  name_create - name of routine to create method context
1597 -  routine_create - routine to create method context
1598 
1599    Level: developer
1600 
1601    Notes:
1602    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1603 
1604    If dynamic libraries are used, then the fourth input argument (routine_create)
1605    is ignored.
1606 
1607    Sample usage:
1608 .vb
1609    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1610                "MyHCreate",MyHCreate);
1611 .ve
1612 
1613    Then, your solver can be chosen with the procedural interface via
1614 $     MatMFFDSetType(mfctx,"my_h")
1615    or at runtime via the option
1616 $     -snes_mf_type my_h
