157 
158    Synopsis:
159    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
160 
161    Not Collective
162 
163    Input Parameters:
164 +  name - name of a new user-defined matrix type
165 .  path - path (either absolute or relative) the library containing this solver
166 .  name_create - name of routine to create method context
167 -  routine_create - routine to create method context
168 
169    Notes:
170    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
171 
172    If dynamic libraries are used, then the fourth input argument (routine_create)
173    is ignored.
174 
175    Sample usage:
176 .vb
177    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
178                "MyMatCreate",MyMatCreate);
179 .ve
180 
181    Then, your solver can be chosen with the procedural interface via
182 $     MatSetType(Mat,"my_mat")
183    or at runtime via the option
184 $     -mat_type my_mat
185

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

1598 
1599    Not Collective
1600 
1601    Input Parameters:
1602 +  name_solver - name of a new user-defined compute-h module
1603 .  path - path (either absolute or relative) the library containing this solver
1604 .  name_create - name of routine to create method context
1605 -  routine_create - routine to create method context
1606 
1607    Level: developer
1608 
1609    Notes:
1610    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1611 
1612    If dynamic libraries are used, then the fourth input argument (routine_create)
1613    is ignored.
1614 
1615    Sample usage:
1616 .vb
1617    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1618                "MyHCreate",MyHCreate);
1619 .ve
1620 
1621    Then, your solver can be chosen with the procedural interface via
1622 $     MatMFFDSetType(mfctx,"my_h")
1623    or at runtime via the option
1624 $     -snes_mf_type my_h
