MATLAB: I am supposed to plot the given figure on matlab

Question

This is what I wrote:

t= -2:0.002:2; f=@(t) (-(t>-2)+t.*(t>-2)-t.*(t>-1)+(t>-1)+(t>0)-(t>1)-t.*(t>1)); plot(t,f(t));

I'm unable to get the correct output.

Answer 1

Try this

t= -2:0.002:2; 
f=@(t)  (t>-2 & t<=-1).*(t+1) + ...
        (t>-1 & t<=0).*1 + ...
        (t>0 & t<=1).*2 + ...
        (t>1 & t<=2).*(-t+2);
plot(t,f(t));
