Convolution of rect (t/2) and δ(t+2) - δ(t+1)

how can i plot this: g(t) = rect(t/2) * [δ(t+2) - δ(t+1)]. As matter of fact, i want to plot the convolution of this functions. But i'm having trouble creating the rect function. If anyone can help me, i would appreciate it very much.

You can make a rect function by making an array of zeros and placing stretch of 1's in it:

rectPulse = zeros(1, 20);
rectPulse(10:15) = 1;
plot(rectPulse, 'bs-');
