Input Parameters

sname - name of coarsen (for example MATCOARSENMIS)
path - location of library where creation routine is
name - name of function that creates the coarsen type, a string
function - function pointer that creates the coarsen type

If dynamic libraries are used, then the fourth input argument (function) is ignored.

Sample usage

   MatCoarsenRegisterDynamic("my_agg",/home/username/my_lib/lib/libO/solaris/mylib.a,
               "MyAggCreate",MyAggCreate);

Then, your aggregator can be chosen with the procedural interface via 

    MatCoarsenSetType(agg,"my_agg")
or at runtime via the option 
    -mat_coarsen_type my_agg
