I am new to matlab and I have to plot this step fucntion but I don't even know where to start.
x(t) = u(t + 1) − 3u(t) + 2u(t−3) with a time interval of -2: 0.1: 2. May I please get some help? The hint was to use heaviside.

Since the unit step functrion is defined as being equal to 1 for , I would use:
Ustp0 = @(t) (t >= 0);
Ustp1 = @(t) 0.5*(t == 0) + 1*(t > 0); % ‘Half-Maximum’ Convention
Plotting the unit step funcitons themselves:
t = -2: 0.1: 2;
figure
subplot(2,1,1)
plot(t, Ustp0(t))
ylim([-0.1 1.1])
subplot(2,1,2)
plot(t, Ustp1(t))
ylim([-0.1 1.1])
So use those to create your function, and and go from there.
I leave the rest to you.
