How do we know if a matrix is diagonalizable

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. WebAmatrixP 2 M n⇥n(R) is orthogonal if its columns form an orthonormal set in Rn. Lemma. P 2 M n⇥n(R) is orthogonal if and only if P 1 = Pt. Pf. The (i,j)-entry of PtP is v i · v j = i,j. Spectral theorem. If A 2 M n(R) is symmetric, then A is diagonalizable over R. Namely, there exists a real diagonal matrix D and an orthogonal matrix P
