165    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
166 
167    Not Collective
168 
169    Input Parameters:
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
174 
175    Notes:
176    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
177 
178    If dynamic libraries are used, then the fourth input argument (routine_create)
179    is ignored.
180 
181    Sample usage:
182 .vb
183    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
184                "MyMatCreate",MyMatCreate);
185 .ve
186 
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
191

193 
194    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
195          If your function is not being put into a shared library then use VecRegister() instead
