For Loop using two variables and plotting

Im pretty new to matlab, the question is Plot sα(t) = (e^(−2))(e^(−αt))* cos(4πt)u(t) for α ∈ {1, 3, 5, 7} in one figure for t = [0 : 0.01 : 4].

this is the code i have written, but it doesnt seem right.

g = inline ('exp(-2*t).*cos(4*pi*t).*(t>=0)','t');

for a=[1:2:7], s= inline ('exp(-a)','a'); end

t= [0:0.01:4]; figure; plot(t,g(t).*s);

Answer 1

g = @(t,a)exp(-2*t).*cos(4*pi*t).*(t>=0)*exp(-a);

t= (0:0.01:4)';
a=(1:2:7); 
y = bsxfun(g,t,a);

figure; plot(t,y);
