square (Signal Processing Toolbox)

Generate a square wave.

Syntax

x = square(t)
x = square(t,duty)

Description

x = square(t) generates a square wave with period 2 for the elements of time vector t. square(t) is similar to sin(t), but creates a square wave with peaks of ±1 instead of a sine wave.

x = square(t,duty) generates a square wave with specified duty cycle, duty. The duty cycle is the percent of the period in which the signal is positive.
