I have a plot as follows. How can I add vertical lines through the peak points (total 3 lines here) in the plot ?

Code:

I have written the code as:

"clear all;

m = 4.48e-26; % mass of Nitrogen molecule

k = 1.38e-23; % Boltzmann Constant

p = 0:2800;

ind = 1;

for T = 300:500:1500;

% constant computation

c1 = 4*pi*(m/(2*pi*k*T))^(3/2);

c2 = m/(2*k*T);

c3 = 3*m*k*T;

u(ind,:) = c1*(p.^2.*exp(-(c2*p.^2)));

%u2(ind,:) = c1*c3*exp(-(3/2))

ind = ind+1;

end

figure(1)

plot(p,u)

xlabel('P')

ylabel('probability')

"
