My Matlab program is not outputting the correct signal

I am trying to output this signal on MATLAB and everything looks fine except for the dirac part. It is supposed to go straight up to y=2 at t=10 but it carries on horizontal. How can I fix this?

t=linspace(0,11,1101);

%create more than 500 time-series values

vs=exp(-4*(t-1)).*heaviside(t-1)+0.5*heaviside(t-5)+2*dirac(t-10);

%Input signal array

t1=linspace(0,22,2201);

plot(t,vs)

xlabel('t')

ylabel('v_s(t)')

title('Input signal')

Your signal goes to Inf at t=10, as expected. This is why you cannot see it in the plot (if you zoom in you should see a missing data point).

You can set the Inf value to a very high value (see the docs):

t=linspace(0,11,1101);
vs=exp(-4*(t-1)).*heaviside(t-1)+0.5*heaviside(t-5)+2*dirac(t-10);
vs(vs == Inf) = 100; % some high valueaxis limits

You can choose the value that it is visible as a sharp peak, but doesn't mess up your axis limits.
