clc
close all 
clear all 
x=1:10;%give your x here
h=0:2:6; %give your h here
m=length(x); 
n=length(h); 
X=[x,zeros(1,n)]; 
H=[h,zeros(1,m)]; 
%convolution
for i=1:n+m-1 
Y(i)=0; 
for j=1:m 
if(i-j+1>0) 
Y(i)=Y(i)+X(j)*H(i-j+1); 
else
display('error');    
end 
end 
end 
stem(Y); 
ylabel('Y[n]'); 
xlabel('n');

You can copy the code to your m file and substitute x and h with your requirements. give x and h as matrices.

That's convolution. Look up the documentation for the matlab function 'conv'.
