Return a periodic sawtooth waveform.
The sawtooth waveform has a period 2*pi, rises from -1 to 1 on the interval 0 to width*2*pi and drops from 1 to -1 on the interval width*2*pi to 2*pi. width must be in the interval [0,1].
Parameters : | t : array_like
width : float, optional

Examples
>>> import matplotlib.pyplot as plt
>>> x = np.linspace(0, 20*np.pi, 500)
>>> plt.plot(x, sp.signal.sawtooth(x))
