147    MatRegisterDynamic - Adds a new matrix type
148 
149    Synopsis:
150    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
151 
152    Not Collective
153 
154    Input Parameters:
155 +  name - name of a new user-defined matrix type
156 .  path - path (either absolute or relative) the library containing this solver
157 .  name_create - name of routine to create method context
158 -  routine_create - routine to create method context
159 
160    Notes:
161    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
162 
163    If dynamic libraries are used, then the fourth input argument (routine_create)
164    is ignored.
165 
166    Sample usage:
167 .vb
168    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
169                "MyMatCreate",MyMatCreate);
170 .ve
171 
172    Then, your solver can be chosen with the procedural interface via
173 $     MatSetType(Mat,"my_mat")
174    or at runtime via the option
175 $     -mat_type my_mat
176 
177    Level: advanced
178 
179    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
180          If your function is not being put into a shared library then use VecRegister() instead

1573 
1574    Not Collective
1575 
1576    Input Parameters:
1577 +  name_solver - name of a new user-defined compute-h module
1578 .  path - path (either absolute or relative) the library containing this solver
1579 .  name_create - name of routine to create method context
1580 -  routine_create - routine to create method context
1581 
1582    Level: developer
1583 
1584    Notes:
1585    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1586 
1587    If dynamic libraries are used, then the fourth input argument (routine_create)
1588    is ignored.
1589 
1590    Sample usage:
1591 .vb
1592    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1593                "MyHCreate",MyHCreate);
1594 .ve
1595 
1596    Then, your solver can be chosen with the procedural interface via
1597 $     MatMFFDSetType(mfctx,"my_h")
1598    or at runtime via the option
1599 $     -snes_mf_type my_h
