How can I represent these graphs as vectors?

Hello,

I have these 2 graphs and I want to represent them as vectors so I can find the convolution between them. This is the first one:

My code:

 t1=0:0.01:3;
 h=ones(size(t1));

The first one is okay but I can't find a way to create the second one:

Any help?

Thanks in advance

figure(1)
t1=0:0.01:3;
h=ones(size(t1));
h(t1==3) = 0;
plot(t1,h,'-b')
xlim([0 4])
ylim([0 2])

figure(2)
t=1:0.01:2;
x=ones(size(t));
x(t==1 | t==2) = 0;
plot(t,x,'-b')
xlim([0 3])
ylim([0 2])
