Statistics about compression achieved in implicit mode.
To enable the user to tune parameters of the implicit build mode of a Dune::BCRSMatrix manually, some statistics are exported upon during the compression step.
double Dune::CompressionStatistics< size_type >::avg |
average number of non-zeroes per row.
Referenced by Dune::BCRSMatrix< B, A >::compress().
size_type Dune::CompressionStatistics< size_type >::maximum |
maximum number of non-zeroes per row.
Referenced by Dune::BCRSMatrix< B, A >::compress().
double Dune::CompressionStatistics< size_type >::mem_ratio |
fraction of wasted memory resulting from non-used overflow area.
mem_ratio is equal to nonzeros()/(# allocated matrix entries)
