a$)$ For $3/8$ marks, copy and paste your MATLAB code that: $($i$)$ loads your individualized data as the matrix A; $($ii$)$ computes the matrix C; $($iii$)$ finds the eigenvalues and eigenvectors of A and of C; and $($iv$)$ displays the results on the MATLAB console; the eigenvalues should be displayed in vector form $($this can be done using the vec function$)$ and the eigenvectors can be displayed in matrix form.

$($b$)$ For $2/8$ marks, provide the eigenvalues, as a vector, of your individualized matrices A and C$.$

$($c$)$ For $1/8$ marks, provide the eigenvectors, as a matrix, of your individualized matrices A and C$.$

$($d$)$ For $2/8$ marks, using one or two simple English sentences, describe how $(1$ mark$)$ and why $(1$ mark$)$ the eigenvalues of A and C differ.
