Why is Time=t declared in this code snippet

The is part of a larger m file, but it's completely independent- time isn't called anywhere else, so, what does the line "time=t" do in this code?

clear all;clc; 
Ts1=0.01;n=1:3:1/Ts1;
t=n*Ts1;
Time=t;
xn1 = sin (2*pi*t);
subplot(3,1,1)
stem(n,xn1)
title('Sin(2pi*t) sampled at Ts=0.01 second intervals');
xlabel('T=n*0.01s');
ylabel('x(n)');

It assigns the vector t to the variable Time.

So "Time" is just a variable (that happens not be used, despite being declared)? That's what I'm getting here- I thought perhaps Time was a function that was doing something else in the code. Thanks.

Correct. It creates a duplicate of t.

Functions would either:

• have no arguments ( consider, relevantly, tic, toc and some others ) or it would return a result without an argument ( clock and friends again )
• take an argument ( in parentheses )

If Time was a function, I would expect the line to be:

t = Time;
t = Time(x);

or something similar.

That the line is:

Time = t;

pretty much guarantees it’s a variable.

Awesome, thanks!

My pleasure!
