Matlab program for Auto Correlation?

AUTOCORRELATION:

 To write a program for Auto Correlation for the given sequence using MATLAB

ALGORITHM:

Step 1: Start
Step 2: Read the input sequence
Step 3: Perform auto correlation using the xcorr() function
Step 4: Plot the sequences
Step 5: Display the input & output sequences
Step 6: Stop
SOURCE CODE:

clc;

close all;

clear all;

x=input('Enter the sequence 1: ');

y=xcorr(x,x);

figure;

subplot(2,1,1);

stem(x);

ylabel('Amplitude->');

xlabel('n->');

title('Input sequence');

subplot(2,1,2);

stem(fliplr(y));

ylabel('amplitude');

xlabel('n->');

title('Output sequence');

disp('the resultant is ');

fliplr(y);
