Suppose we want to simulate this oscillator from $=0$

t

$=$

$0$

to $=20$

t

$=$

$20$

with the time increment $\backslash$Delta $$

$\backslash$Delta

t

set to $0\mathrm{.}05$

$0\mathrm{.}05$

$.$ Create this time array called t$.$ It shoud start at $0$ and end at $20($inclusive$)$ with an increment of $0\mathrm{.}05$

$0\mathrm{.}05$

$.$ Then save the length of t to a variable called N$.$
