I am trying to plot this code :
clc;clear all;close all;
n=3;
t=linspace(0,24*n,100e3*n);
y1=cos(t*(pi/3))+sin(t*(pi/4));
plot(t,y1);
hold on;
plot(24*1,y1(1*100e3),'*');
hold on;
plot(24*2,y1(2*100e3),'*');
hold on;
plot(24*3,y1(3*100e3),'*');
using for loop but for some reason I get only the last plot .
this is my code using for loop:
clc;clear all;close all;
n=3;
t=linspace(0,24*n,100e3*n);
y1=cos(t*(pi/3))+sin(t*(pi/4));
plot(t,y1)
hold on;
for i=1:n
hold on;
plot(24*n,y1(n*100e3),'*');
hold on
end
hold off
where is my problem ?

plot(24*i,y1(i*100e3),'*');
plot(24*n,y1(n*100e3),'*');
