Common Periodic Waveforms
The toolbox provides functions for generating widely used periodic waveforms:
sawtooth generates a sawtooth wave with peaks at ±1 and a period of 
. An optional width parameter specifies a fractional multiple of 
at which the signal's maximum occurs.square generates a square wave with a period of 
. An optional parameter specifies duty cycle, the percent of the period for which the signal is positive.To generate 1.5 seconds of a 50 Hz sawtooth wave with a sample rate of 10 kHz and plot 0.2 seconds of the generated waveform, use
fs = 10000; t = 0:1/fs:1.5; x = sawtooth(2*pi*50*t); plot(t,x), axis([0 0.2 -1 1])
