tempusSystem Class TimeHistory2
TimeHistory2 is part of the WaveTrain system class library

TimeHistory2 outputs a time-dependent 2x1 Vector< float > value given two input signal vector vx and vy having lengths nt and corresponding time vector tv with length nt. The output value is chosen based on the current time; if the current time falls between two times in the time vector, the output value is chosen by interpolating the input signal vectors (if sampleFlag = 0), or by sample-and-hold (if sampleFlag != 0). The parameter t0 defines the start time in the time vector, so that at simulation time t = 0.0 s, the output grid will be that for tv = t0. Also, the input time vector may be defined such that the time history does not begin until t > 0.0 s, and in prior times the initial values vx0 and vy0 are used. If the time vector ends before the end of the simulation, the last value is held throughout the remainder of the simulation.
