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]')

If y has values from n=[0,101], then in order for the two inputs of stem to be the same length, you can say
stem(0:50, y(1:51), 'r-')
This includes the first 51 values of y that are for n=[0,50].
