I am studying Toeplitz matrices. I have to find out the eigenvalues of the following Toeplitz matrix:
$$\begin{bmatrix} 2 & -8 & -24 \\ 3 & 2 & -8 \\ 1 & 3 & 2 \end{bmatrix}$$
Are there any different procedures to find out eigenvalues of Toeplitz matrices? Can't I use the general method of finding eigenvalues for them too? I need help with this. I need matlab code also. Edit: I was studying this paper http://www.sciencedirect.com/science/article/pii/0024379574900044
Thanks for help.
