121    MatRegisterDynamic - Adds a new matrix type
122 
123    Synopsis:
124    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
125 
126    Not Collective
127 
128    Input Parameters:
129 +  name - name of a new user-defined matrix type
130 .  path - path (either absolute or relative) the library containing this solver
131 .  name_create - name of routine to create method context
132 -  routine_create - routine to create method context
133 
134    Notes:
135    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
136 
137    If dynamic libraries are used, then the fourth input argument (routine_create)
138    is ignored.
139 
140    Sample usage:
141 .vb
142    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
143                "MyMatCreate",MyMatCreate);
144 .ve
145 
146    Then, your solver can be chosen with the procedural interface via
147 $     MatSetType(Mat,"my_mat")
148    or at runtime via the option
149 $     -mat_type my_mat
150 
151    Level: advanced
152 
153    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
154          If your function is not being put into a shared library then use VecRegister() instead

1507 
1508    Not Collective
1509 
1510    Input Parameters:
1511 +  name_solver - name of a new user-defined compute-h module
1512 .  path - path (either absolute or relative) the library containing this solver
1513 .  name_create - name of routine to create method context
1514 -  routine_create - routine to create method context
1515 
1516    Level: developer
1517 
1518    Notes:
1519    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1520 
1521    If dynamic libraries are used, then the fourth input argument (routine_create)
1522    is ignored.
1523 
1524    Sample usage:
1525 .vb
1526    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1527                "MyHCreate",MyHCreate);
1528 .ve
1529 
1530    Then, your solver can be chosen with the procedural interface via
1531 $     MatMFFDSetType(mfctx,"my_h")
1532    or at runtime via the option
1533 $     -snes_mf_type my_h
