@ungarlinski7965 There is a fun problem related to this that I wrote a paper on! imagine that the sub and super diagonals have entries which are geometrically decreasing. Do the eigenvalues of the nxn matrix and (n-1)\times(n-1) matrix interlace? Cool stuff!
@@mikethemathematician Know that I was only kidding earlier. So the paper answers that? Is that your own question? I only know of tridiagonal matrices from Terwilliger at Madison.
Pfft. Child's play
