how to plot random ones and zeros as sequare wave?

i am trying to plot my random binary signal as square wave using these simple code

s=rand(1,10)>0.5;
t=1:1:10;
plot(t,s);

but its appear as triangle wave as shown below

n=20
s=rand(1,n)>0.5;
s=repmat(s',1,100)'
s=s(:)'
t=linspace(0,n,numel(s))
plot(t,s,'r')

Excuse me, could you help me to generate triangle signal starts from 0 to 60 degree and stops and then starts from 120 to 180 and then repeat itself, either by coding or simulink, please?

It is better to use stem() for this purpose

 s=rand(1,10)>0.5;
 t=1:1:10;
 stem(t,s,'markerfacecolor',[0 0 1])
