I need to use it in this code
clear; clc; close all
n = 4; % Number of symbol intervals
M = 16; % Use M-ary modulation
Fd = 1; % Sampling rate of the message signal
Fs = 100; % Sampling rate of the modulated signal
fc = 18; % Carrier frequency
x = randi([0 M-1],n,1); % Random multilevel message signal (from zero to M-1)
xt = reshape(repmat(x,1,Fs)',1,n*Fs); t = 1:1:n*Fs; % Arrange time axis
% PAM (ASK) Signals
% A) Baseband ASK
sask = real(dmodce(x,Fd,Fs,'ask',M));
modmap('ask',M);
set(gcf,'Color',[1 1 1])
pause
subplot(2,1,1);
plot(t,xt);
title('Input signal x(t) as M-ary levels')
axis ([min(t) max(t) -0.1 max(x)*1.1])
set(gca,'XTick',[50 100 150 200 250 300 350 400])
set(gca,'XTickLabel',{'T/2';'T';'3T/2';'2T';'5T/2';'3T';'10T/2';'4T'},'FontWeight','bold');
subplot(2,1,2); plot(t,sask); title('ASK baseband signal - s_m(t)'); xlabel('Time Axis')
axis ([min(t) max(t) -1.1 1.1])
set(gca,'XTick',[50 100 150 200 250 300 350 400])
set(gca,'XTickLabel',{'T/2';'T';'3T/2';'2T';'5T/2';'3T';'10T/2';'4T'},'FontWeight','bold');
pause; clf reset
% B) Bandpass PAM (ASK)
uask = dmod(x,fc,Fd,Fs,'ask',M);
subplot(2,1,1); plot(t,sask); set(gcf,'Color',[1 1 1])
title('ASK baseband signal - s_m(t)')
axis ([min(t) max(t) -1.1 1.1])
set(gca,'XTick',[50 100 150 200 250 300 350 400])
set(gca,'XTickLabel',{'T/2';'T';'3T/2';'2T';'5T/2';'3T';'10T/2';'4T'},'FontWeight','bold');
subplot(2,1,2); plot(t,uask); title('ASK bandpass signal - u_m(t)'); xlabel('Time Axis')
axis ([min(t) max(t) -1.1 1.1])
set(gca,'XTick',[50 100 150 200 250 300 350 400])
set(gca,'XTickLabel',{'T/2';'T';'3T/2';'2T';'5T/2';'3T';'10T/2';'4T'},'FontWeight','bold');
pause
