Detailed Description

template<int D>
class Pscf::Rpg::AverageAnalyzer< D >

Analyze averages and block averages of several real variables.

This class evaluates the average of a single sampled real variables, and optionally writes values or block averages to a data file during a simulation. It is intended for use as a base class for any Analyzer that computes and evaluates an average for a single physical variable.

Specializations of this template with D=1, 2, and 3 are derived from specializations of the base class template Rp::AverageAnalyzer, and inherit their public interface and almost all of their source code from this base class.
