| May 25, 2014 at 23:59 | comment | added | Gerry Myerson | There is no theorem that guarantees that a tridiagonal matrix has a real eigenvalue. $$\pmatrix{0&1&0&0\cr-1&0&0&0\cr0&0&0&1\cr0&0&-1&0\cr}$$ | |
| May 25, 2014 at 23:55 | comment | added | Dima Pasechnik | it would help a lot if you spend few minutes typesetting entries in a readable way: e.g. the diagonal entry $M_{i+1,i+1}=1+4i-i^2-2n$ for all $i$ between 0 and $n-1$. | |
