Can someone please find and plot the Fourier Transform of y,x(i) and b signals from the below code... y is Gate function , x(i) is train of impulse and b is sampled signal

T = -5:0.01:5;
y = rectpuls(T,2);
subplot(2,2,1);
plot(T,y);
xlabel('Time');
ylabel('Amplitude');
title('Gate Function');
grid on;
n= -5:1:5;
L =length(n);

for i= 1:L
    x(i)=1;
end;

subplot(2,2,2);
stem(n,x);

xlabel('Time');  
ylabel('Amplitude');
title('Train of Impulses');
grid on;
t=-5:0.01:5;
b=y.*x(i);
subplot(2,2,3);
stem(t,b);
xlabel('Time');
ylabel('Amplitude');
title('Sampled Signal');
grid on;

Harshit - you have provided a number of lines of code but have not indicated where or what the problem is. Does the above code fail (is there an error?) or not produce the result that you are looking for?
