property of Dirac delta function in matlab

hey guys!

hello

i want to plot the property of Dirac delta function in matlab;

my uncompleted code:

clc
clear all

t=0:0.01:2*pi;
x1=2*sin(t);

subplot(311)
plot(t,x1);grid


x = -1:0.1:1;
y = dirac(x);
idx = y == Inf;
y(idx) = 1;    

subplot(312)
stem(x,y);grid

final=x1.*y;
subplot(312)
plot(t,final);grid

result

my final answer:
