How to do a damped sine wave

Hi I am trying to do a damped sine wave, but my program is not working. Can someone please tell me what I am doing wrong? Here is my code.

A=10;f=1000;n=5;T=1/f;t=[0:T/100:n*T];s=A*exp(-t).*sin(2*pi*f*t);

plot(t,s)

Hi Walter!

I laughed out loud when I read your comment!

Hi. Include some constant in "exp(-t)" part of your function. Make it like exp(-B.*t) and choose B = 1000 or any other value depending on how much damping you want.

Please describe ‘not working’.

It runs without error for me, and plots the appropriate sine curve. If it’s not damping quickly enough for you, multiply the ‘-t’ in the exponential by some constant (here 1000). Change the constant to produce the result you want.

For example:

A=10;f=1000;n=5;T=1/f;t=[0:T/100:n*T];s=A*exp(-t*1000).*sin(2*pi*f*t);
