Put Zero Value randomly in wave function

So i have a sin wave function and i want to put zero value number randomly into the wave function. Is that possible and how to ?

%Sine wave 
freq=400;
Amp=2;
t_samp=1/8000;
T=0.01;
t=0:t_samp:T;
y=Amp*sin(2*pi*freq*t);
subplot(2,1,1);
plot(t,y)
ylabel ('Amplitude');
xlabel ('Time');
title ('Sine wave');

Try something like this —

%Sine wave 
freq=400;
Amp=2;
t_samp=1/8000;
T=0.01;
t=0:t_samp:T;
y=Amp*sin(2*pi*freq*t);
y(randi(numel(y))) = 0;                                 % Random Value (Index) = 0
subplot(2,1,1);
plot(t,y)
ylabel ('Amplitude');
xlabel ('Time');
title ('Sine wave');

.

Yes it is possible. You can put zero value by making random value index of y.

%Sine wave 
freq=400;
Amp=2;
t_samp=1/8000;
T=0.01;
t=0:t_samp:T;
y=Amp*sin(2*pi*freq*t);
y(randi([1 numel(y)],1,10)) = 0; % ----- here
subplot(2,1,1);
plot(t,y)
ylabel ('Amplitude');
xlabel ('Time');
title ('Sine wave');
