alfa=5/3; tau1=2
E=-alfa .*exp(-tau1) + alfa
t1=0:0.1:4.4;
plot(t1,E)
plot(t1,E,'Linewidth', 2)

Your E is a scalar constant independent of t.

alfa = 5/3;
tau1 = 2;
gamma = 1/sqrt(9.8085);
EeA = @(tau) -alfa .* exp(-tau) + alfa;
Ee1 = @(tau) ones(size(tau)) .* (-alfa .* exp(-tau1) + alfa);
EeB = @(tau) gamma .* exp(-(tau - tau1)) - alfa;
t = 0:0.1:4.4;
plot(t, EeA(t), '-k', t, Ee1(t), 'r^', t, EeB(t), '-b');
legend({'E_e(A)', 'E_{e_1}', 'E_e(B)'})
