- generates a periodic square wave with period 2pi for the elements of time vector t.
- generates a square wave with specified duty cycle, duty. The duty cycle is the percent of the period in which the signal is positive.
- generates a sawtooth wave with period 2pi for the elements of time vector t.
– generates a modified triangle wave where width, a scalar parameter between 0 and 1, determines the point between 0 and 2pi at which the maximum occurs.
- returns a continuous, aperiodic, symmetric, unity-height triangular pulse at the times indicated in array t, centered about t = 0 and with a default width of 1.
