Generate random numbers per second

Hi, I want to generate random numbers per second in range of 1 to 20 and also draw them on a graph immediately. How can I code this in MATLAB? THX

What does this mean (the "per second part at least)???

The code for your question might be like this. But I'm not sure why this kind of code is needed... (I would be happy if you could tell us more detail behind your question! )

data = [];
figure
for kk = 1:100
   data = [data, randi(20)];
   plot(data,'o-');
   pause(1);
end

Take a look at the rand, randn, or randi functions in MATLAB or the random number generation functions in Statistics and Machine Learning Toolbox (depending on the distribution from which you want to draw your random numbers.)

For the plotting, see if animatedline does what you want.
