TimeHistoryVF outputs a time-dependent Vector< float > given an input signal array sa having dimension (nx,nt) and corresponding time vector tv with dimension (nt). The output vector is chosen based on the current time; if the current time falls between two times in the time vector, the output vector is chosen by interpolating the input signal array (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 vector 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 vector s0 is used. If the time vector ends before the end of the simulation, the last vector is held throughout the remainder of the simulation.
