164    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
165 
166    Not Collective
167 
168    Input Parameters:
169 +  name - name of a new user-defined matrix type
170 .  path - path (either absolute or relative) the library containing this solver
171 .  name_create - name of routine to create method context
172 -  routine_create - routine to create method context
173 
174    Notes:
175    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
176 
177    If dynamic libraries are used, then the fourth input argument (routine_create)
178    is ignored.
179 
180    Sample usage:
181 .vb
182    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
183                "MyMatCreate",MyMatCreate);
184 .ve
185 
186    Then, your solver can be chosen with the procedural interface via
187 $     MatSetType(Mat,"my_mat")
188    or at runtime via the option
189 $     -mat_type my_mat

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