Matlab program to find the linear convolution of two signals (using matlab functions)

Program Code

%linear convolution (using matlab functions)
clc;
close all;
clear all;
x1=input('Please enter the input sequence x[n]= ');
x2=input('Please enter the starting time index of x[n]= ');
h1=input('Please enter the impulse response h[n]= ');
h2=input('Please enter the starting time index of h[n]= ');
y=conv(x1,h1);
n=x2+h2:length(y)+x2+h2-1;
display('The convoluted sequence is given below:');
y
stem(n,y);
xlabel('Time');
ylabel('Amplitude');
title('Linear Convolution');

Example of Output

Please enter the input sequence x[n]= [4 3 1 2]
Please enter the starting time index of x[n]= -2
Please enter the impulse response h[n]= [1 4 3]
Please enter the starting time index of h[n]= -1
The convoluted sequence is given below:

y =


     4    19    25    15    11     6
