t=(-1:0.001:5);
u=@(t) t>0;
h1=(2).*(heaviside(t)-heaviside(t-1));
h2=(4).*(heaviside(t)-heaviside(t-2));
h12 = conv(h1,h2);
ht= h1+h12;
% Plot out h1*h2
figure(1)
subplot(1, 1,1 );
plot(t,ht, 'b-', 'LineWidth', 2); % Just plot vs. index.
grid on;
title('Signal h(t)');
xlabel('time', 'FontSize', 12);
ylabel('amplitude h(t)', 'FontSize', 12);

Try the following change in conv() call on line 5.
h12 = conv(h1,h2,'same');
