In that image the times where the wave rises or fall is not well specified, but asuming that the width of the pulse is 2, then you can do it this way:

Code: 
t=-6:0.01:6;
signal = zeros(size(t));


for n = 1:length(t)
   
   if (abs(t(n)) <= 1 | (abs(t(n)) >= 3 & abs(t(n)) <= 5))
      signal(n) = 2;
   end
end

plot(t,signal)

You can also calculate the fourier series, and build the signal up from it.

Hope this helps.
