00033 // PulseSeries is a concrete class. A PulseSeries object provides
00034 // a pulse time series. The factor is given by the pseudoTime (t),
00035 // pulse period (T), pulse width (pw) and phase shift (phi),
00036 // and a constant factor provided in the constructor,
00037 // the duration by tStart and tFinal;
