Hey I want to dis play my signal which has values from n=[0,101] only from n=[0,50] but when i try it tells me x must be the same length as y here is my code.
clc; close all;
z = conv(x,h);
figure(2)
stem(0:1:51, y, 'r -');
hold on
stem(0:1:101, z, 'bo ')
xlabel('n');
ylabel('z[n]');
title('z[n] vs y[n]');
legend('y[n]','z[n]')

Your y variable clearly doesn't have 52 elements in it. Or z doesn't have 102.
Without showing us your variables, how are we supposed to help?
Try running whos or size(y) or size(z).
