round2sample

  ROUND2SAMPLE - Round a continuous point to the nearest sampled value for a regularly sampled signal

    TR = ROUND2SAMPLE(TI,DT[, T0])

    Given a signal sampled at regular intervals DT, and given a set of time points TI,
    calculates the closest sample times TR that are multiples of DT.
    T0 is the time of the first sample. If it is not provided then it is assumed to be 0. 

    Example:
        DT = 0.001;
        TI = 0.00100000001;
        TR = ROUND2SAMPLE(TI, DT)   % returns 0.001
