Detailed Description

template<typename T>
class Dune::PDELab::SolverStatistics< T >

Class for collecting statistics over several invocations.

Records data for every invocation and provides methods for calculating min/max/avg/stddev over all invocations. This can then be used to calculate statistics on the block-solves
