Hello, I want to plot function of sound wave
y=A1sinh(2pift)^2-1.Asin(2pift)
The code that I have written is given below
clc;
clear all;
close all;
fs=2400; %sampling frequencyy=
f1=0.5; %frequency of the sound wave
f2=200;
A1=1
A2=1
t=0:10/fs:1;
y=((A1*sinh(2*pi*f1*t).^2)-1).*(A2*sin(2*pi*f2*t));
plot(t,y)
sound(y);

It is working right? What question you have specifically?

it is working, but sound is not produced .
Plot is right that I want to obtain , but sound is not produced.

I checked the code on my laptop, the code runs fine and it produces a sound as well, but just a short beep.
(Increase your sampling frequency to get a longer sound or use earphones to hear the sound)

Try this:
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 15;
markerSize = 30;
fprintf('Beginning to run %s.m ...\n', mfilename);
Beginning to run LiveEditorEvaluationHelperEeditorId.m ...
fs=2400; % sampling frequency
f1=0.085; % frequency of the sound wave
f2=200;
A1=1;
A2=1;
t = 0 : 1/fs : 5;
y=((A1*sinh(2*pi*f1*t).^2)-1).*(A2*sin(2*pi*f2*t));
plot(t,y)
grid on;
xlabel('Time', 'FontSize',fontSize)
ylabel('Signal', 'FontSize',fontSize)
drawnow;
soundsc(y);
I'm also attaching an old demo of mine.
