Highly effective polynomial root-finders have been recently designed based on eigen-solving for DPR1 (that is diagonal + rankone) matrices. We extend these algorithms to eigen-solving for the general matrix by reducing the problem to the case of the DPR1 input via intermediate transition to a TPR1 (
