MATLAB: How to plot two functions in the same diagramm

plot both function

I will plot both function in the same diagramm? What is wrong?
 clear all, close all, clc
v=1000*0.005*0.995; %Varianz
sigma = sqrt(v);   %Standardabweichung
mu = 1000*0.005;        %Erwartungswert
dt = 0.1;     %Schrittweite
t = 0:dt:10;
Phi(1)= 0;       %Startwert
for n=1:length(t),
    %Dichtefunktion
    phi(n)=1/(sqrt(2+pi)*sigma)*exp(-(t(n)-mu)^2/(2*sigma^2));
    %Rechteckintegration
    Phi(n+1) = Phi(n) + phi(n)*dt;
end
%Darstellung
p=1-Phi(end),
figure(1),
plot(t,phi),grid on,
title('Glockenkurve der gaußschen Normalverteilung'),
xlabel('Samenkörner');
ylabel('Dichtefunktion');

Best Answer

plot(t, phi, t, Phi)
In general you can also use
plot(t, phi)
hold on
plot(t, Phi)
hold off
