Find an $n\times n$ real symmetric five-diagonal matrix $A$ such that $$Ax=\alpha x,\quad Ay=\beta y,\quad Az=\gamma z.$$ The solvability is investigated. A numerical algorithm is presented. The besic idea is: Constructing a Jacobi matrix $J$ first, then obtained the desired matrix $A= J^2- pI_n$.}, reviewer = {Liu Xinguo (Qingdao)}, identifier = {01921318}, }
