How to diagonalize a matrix with eigenvalues
WebDiagonalize the given 2×2 matrix: A = [ 1 / 2 3 / 2 3 / 2 1 / 2] Solution: First, calculate the characteristic polynomial to find the Eigenvalues and Eigenvectors. Hence, f (λ)= λ 2 – Tr (A)λ + det (A) = λ 2 – λ – 2 = (λ+1) (λ-2) Thus, the Eigenvalues are -1 and 2. Now, we have to calculate the Eigenvector for every Eigenvalue. Thus, if λ 1 = -1, WebHow do you check a matrix is diagonalizable or not? According to the theorem, If A is an n×n matrix with n distinct eigenvalues, then A is diagonalizable. We also have two eigenvalues λ1=λ2=0 and λ3=−2. For the first matrix, the algebraic multiplicity of the λ1 is 2 and the geometric multiplicity is 1.
