WebMar 24, 2024 · Matrix Eigenvalues Matrix Diagonalization Matrix diagonalization is the process of taking a square matrix and converting it into a special type of matrix--a so-called diagonal matrix --that shares the same fundamental properties of the underlying matrix. WebIgor Konovalov. 10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment.
