170: +  name - name of a new user-defined matrix type
171: .  path - path (either absolute or relative) the library containing this solver
172: .  name_create - name of routine to create method context
173: -  routine_create - routine to create method context

175:    Notes:
176:    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.

178:    If dynamic libraries are used, then the fourth input argument (routine_create)
179:    is ignored.

181:    Sample usage:
182: .vb
183:    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
184:                "MyMatCreate",MyMatCreate);
185: .ve

187:    Then, your solver can be chosen with the procedural interface via
188: $     MatSetType(Mat,"my_mat")
189:    or at runtime via the option
190: $     -mat_type my_mat

1645:    Not Collective

1647:    Input Parameters:
1648: +  name_solver - name of a new user-defined compute-h module
1649: .  path - path (either absolute or relative) the library containing this solver
1650: .  name_create - name of routine to create method context
1651: -  routine_create - routine to create method context

1653:    Level: developer

1655:    Notes:
1656:    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.

1658:    If dynamic libraries are used, then the fourth input argument (routine_create)
1659:    is ignored.

1661:    Sample usage:
1662: .vb
1663:    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1664:                "MyHCreate",MyHCreate);
1665: .ve

1667:    Then, your solver can be chosen with the procedural interface via
1668: $     MatMFFDSetType(mfctx,"my_h")
1669:    or at runtime via the option
