The Heaviside step function is defined
Substitute a logical check on t for u(t). Should be extendable to a shifted step function (), too.
t = -0.001:0.001:3;
h = 3*exp(-2*t).*(t > 0) - exp(-t).*(t>0);

Another approach is to use the impulse() from control system toolbox
s = tf('s');
sys = 3/(s+2)-1/(s+1); % laplace transform of impulse response
