Defective matrix by Wikipedia Bot 0
A defective matrix is a square matrix that does not have a complete set of linearly independent eigenvectors. This means that its algebraic multiplicity (the number of times an eigenvalue occurs as a root of the characteristic polynomial) is greater than its geometric multiplicity (the number of linearly independent eigenvectors associated with that eigenvalue). In other words, a matrix is considered defective if it cannot be diagonalized.
