142    MatRegisterDynamic - Adds a new matrix type
143 
144    Synopsis:
145    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
146 
147    Not Collective
148 
149    Input Parameters:
150 +  name - name of a new user-defined matrix type
151 .  path - path (either absolute or relative) the library containing this solver
152 .  name_create - name of routine to create method context
153 -  routine_create - routine to create method context
154 
155    Notes:
156    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
157 
158    If dynamic libraries are used, then the fourth input argument (routine_create)
159    is ignored.
160 
161    Sample usage:
162 .vb
163    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
164                "MyMatCreate",MyMatCreate);
165 .ve
166 
167    Then, your solver can be chosen with the procedural interface via
168 $     MatSetType(Mat,"my_mat")
169    or at runtime via the option
170 $     -mat_type my_mat
171 
172    Level: advanced
173 
174    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
175          If your function is not being put into a shared library then use VecRegister() instead

1576 
1577    Not Collective
1578 
1579    Input Parameters:
1580 +  name_solver - name of a new user-defined compute-h module
1581 .  path - path (either absolute or relative) the library containing this solver
1582 .  name_create - name of routine to create method context
1583 -  routine_create - routine to create method context
1584 
1585    Level: developer
1586 
1587    Notes:
1588    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1589 
1590    If dynamic libraries are used, then the fourth input argument (routine_create)
1591    is ignored.
1592 
1593    Sample usage:
1594 .vb
1595    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1596                "MyHCreate",MyHCreate);
1597 .ve
1598 
1599    Then, your solver can be chosen with the procedural interface via
1600 $     MatMFFDSetType(mfctx,"my_h")
1601    or at runtime via the option
1602 $     -snes_mf_type my_h
