150    MatRegisterDynamic - Adds a new matrix type
151 
152    Synopsis:
153    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
154 
155    Not Collective
156 
157    Input Parameters:
158 +  name - name of a new user-defined matrix type
159 .  path - path (either absolute or relative) the library containing this solver
160 .  name_create - name of routine to create method context
161 -  routine_create - routine to create method context
162 
163    Notes:
164    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
165 
166    If dynamic libraries are used, then the fourth input argument (routine_create)
167    is ignored.
168 
169    Sample usage:
170 .vb
171    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
172                "MyMatCreate",MyMatCreate);
173 .ve
174 
175    Then, your solver can be chosen with the procedural interface via
176 $     MatSetType(Mat,"my_mat")
177    or at runtime via the option
178 $     -mat_type my_mat
179 
180    Level: advanced
181 
182    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
183          If your function is not being put into a shared library then use VecRegister() instead

1587 
1588    Not Collective
1589 
1590    Input Parameters:
1591 +  name_solver - name of a new user-defined compute-h module
1592 .  path - path (either absolute or relative) the library containing this solver
1593 .  name_create - name of routine to create method context
1594 -  routine_create - routine to create method context
1595 
1596    Level: developer
1597 
1598    Notes:
1599    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1600 
1601    If dynamic libraries are used, then the fourth input argument (routine_create)
1602    is ignored.
1603 
1604    Sample usage:
1605 .vb
1606    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1607                "MyHCreate",MyHCreate);
1608 .ve
1609 
1610    Then, your solver can be chosen with the procedural interface via
1611 $     MatMFFDSetType(mfctx,"my_h")
1612    or at runtime via the option
1613 $     -snes_mf_type my_h
