    This function is a wrapper for the __neg__ function in the StateSpace and
    TransferFunction classes.  The output type is the same as the input type.

    If both systems have a defined timebase (dt = 0 for continuous time,
    dt > 0 for discrete time), then the timebase for both systems must
    match.  If only one of the system has a timebase, the return
    timebase will be set to match it.

    Examples
    --------
    >>> sys2 = negate(sys1) # Same as sys2 = -sys1.
