WebGeometrically, a diagonalizable matrix is an inhomogeneous dilation (or anisotropic scaling) — it scales the space, as does a homogeneous dilation, but by a different factor along each eigenvector axis, the factor given by the corresponding eigenvalue. A square matrix that is not diagonalizable is called defective. WebJun 15, 2024 · Take the diagonal matrix A = [3 0 0 3] A has an eigenvalue 3 of multiplicity 2. We call the multiplicity of the eigenvalue in the characteristic equation the algebraic multiplicity. In this case, there also exist 2 linearly independent eigenvectors, [1 0] and [0 1] corresponding to the eigenvalue 3.
