Hello, total beginner here. Working on fibonacci sequence and assignment says to indicate which numbers are a multiple of 3. Here's what I have:
function f=fibo(n)
if n<=1
f=1;
else
f=fibo(n-1)+fibo(n-2);
end
I want the output of my script to look like this vertically:
1
1
2
3 is a multiple of 3
5
8
...
I used a function m-file and have the answers displayed without the comment. I know I should use if and rem() to add the comment. So I want to attach the comment and also make my output a vertical list.
Thanks!

Use fprintf():
fprintf('This variable = %d\n', someValue);
You can display whatever text you want to the command window with fprintf().
