Write a program in matlab to compute discrete convolution of two sequences.

%Program to find the linear convolution of two sequences

x1=input('Enter the first sequence x1(n) = ')
t1=input('Enter the starting time of first sequence t1 = ')
x2=input('Enter the second sequence x2(n) = ')
t2=input('Enter the starting time of second sequence t2 = ')
l1=length(x1)
l2=length(x2)
ln=l1+l2-1

yn=conv(x1,x2)
a=t1+l1-1
t=t1:a

%output

%Enter the first sequence x1(n) = [1 2 6 2 3 1 4]
%Enter the starting time of first sequence t1 = -3
%Enter the second sequence x2(n) = [3 1 4 5 2]
%Enter the starting time of second sequence t2 = -1
