t = -10:0.01:10;
f = inline('4*hardlim(t+4)-poslin(t+4)+2*poslin(t)-poslin(t-2)-2*hardlim(t-2)', 't')

f =

     Inline function:
     f(t) = 4*hardlim(t+4)-poslin(t+4)+2*poslin(t)-poslin(t-2)-2*hardlim(t-2)

subplot(2,2,1);
plot(t, f(t));
subplot(2,2,2);
plot(t, f(2.*t));
subplot(2,2,3);
plot(t, f(t/1.5));
subplot(2,2,4);
plot(t, f(-t+3));

You have a typo error for the function postlin instead of poslin. see the ref below
