| Jul 14, 2021 at 21:04 | comment | added | Joseph Van Name | Here is an example that has some interesting properties mathoverflow.net/a/396795/22277. Let $\rho_{f}$ denote the permutation matrix for permutation $f$. If $C_{n,r}$ is the $n\times n$-matrix where $C_{n,r}=(I_{n}+r\rho_{(r,r+1)})/(r+1)$, then $C_{n,1}\dots C_{n,n-1}$ is a doubly stochastic matrix with minimal polynomial $x^{n-1}(x-1)$ that is not diagonalizable. | |
