Right now I have a function h = sin(2*pi*50*t) with 27 samples, and I want to add 500 zeros to the end of the 27-signal-long signal. How can I mke it?
fs = 250;
t = (0:1/fs:(0.108-.5/fs)); % [0, 0.108)
h = sin(2*pi*50*t);
L = 27;
f = fs*(0:L-1)/L;

If h is your signal, assign the last element to be zero
h(527) = 0;
The in between values will be automatically filled with zeros.

Thanks for your answer, but in this case how can I modify my code to make it?

clc
clear all
close all
fs = 250;
t = (0:1/fs:(0.108-.5/fs)); % [0, 0.108)
h = sin(2*pi*50*t);
L = 27;
f = fs*(0:L-1)/L;
h(527) = 0;
