An n x n matrix A is said to be diagonalizable if there exists a nonsingular matrix X and a diagonal matrix D such that
(X^-1)(A)(X) = D
Furthermore, if A is diagonalizable, then the column vectors of the diagonalizing matrix X are eigenvectors of A, and the diagonal elements of D are the corresponding eigenvalues of A.
(In other words, I have a linear algebra test tomorrow...)
