示例1: __init__

"""
Constructor.
Args:
amplitude (np.ndarray): amplitude of the square wave;
period (float): time corresponding to one cycle;
timestep (float): time corresponding to each step of simulation;
duty (float, 0.5): value between 0 and 1 and determines the relative
time that the step transition occurs between the start and the
end of the cycle;
offset (float, 0): increment of velocity to each velocity value;
phase (float, 0): angle in rads of the phase of the sine wave.
