WebAug 9, 2024 · Where Q is a matrix comprised of the eigenvectors, diag(V) is a diagonal matrix comprised of the eigenvalues along the diagonal (sometimes represented with a capital lambda), and Q^-1 is the inverse of the matrix comprised of the eigenvectors. However, we often want to decompose matrices into their eigenvalues and eigenvectors. 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. biscotti shift dressWebJun 23, 2024 · Given the matrix.
