problem 2:
Result from codin" rel="nofollow">ing:
Highest eigenvalue:3.6412

Codin" rel="nofollow">ing for problem 2 and 3:
clear all; close all, clc;
A= [1 1 0 1 1; 1 1 0 0 0; 0 0 1 1 1; 1 0 1 1 1; 1 0 1 1 1];

What is an eigenvalue? How does it relate to its eigenvector? Interpret the largest
eigenvalue and its eigenvector pair in" rel="nofollow">in the problem above in" rel="nofollow">in the context of our movie
ratin" rel="nofollow">ings in" rel="nofollow">in relation to genre.
(b) If the origin" rel="nofollow">inal matrix represents lms that you enjoyed, what would our eigenvector
imply about lms you would like to watch in" rel="nofollow">in the future? (Hin" rel="nofollow">int: Consider the direction
of the eigenvector - towards which movies is it poin" rel="nofollow">intin" rel="nofollow">ing and why? In other words, what
are the rows correspondin" rel="nofollow">ing to the most promin" rel="nofollow">inent members of your eigenvector? These
are the \top" movies highlighted by our algorithm.)
(c) Why, in" rel="nofollow">in our analysis, is Robin" rel="nofollow">in Hood classied as a lower title than, say, Shrek, even
though they have the same number of relationships to other lms in" rel="nofollow">in the matrix?
