I would like to generate rectangular wave through matrices. I am able to generate triangular signal by :

tri=[0 1/3 2/3 1 2/3 1/3 0 0];

Any idea on how to generate a rectangular wave in this method? thanks.

t=-10:0.01:10;
y=heaviside(t+5)-heaviside(t-5),
plot(t,y)

If you do not have heaviside function use

t=-10:0.01:10;
echelon=@(x) (1+sign(x))/2
y=echelon(t+5)-echelon(t-5),
plot(t,y)
