WebWe say an eigenvalue, , is repeated if almu( ) 2. Algebraic fact, counting algebraic multiplicity, a n nmatrix has at most nreal eigenvalues. If nis odd, then there is at least one real eigenvalue. The fundamental theorem of algebra ensures that, counting multiplicity, such a matrix always has exactly ncomplex eigenvalues. Eigenvalues and eigenvectors give rise to many closely related mathematical concepts, and the prefix eigen-is applied liberally when naming them: The set of all eigenvectors of a linear transformation, each paired with its corresponding eigenvalue, is called the eigensystem of that transformation. See more In linear algebra, an eigenvector or characteristic vector of a linear transformation is a nonzero vector that changes at most by a scalar factor when that linear transformation is applied to it. The corresponding … See more Eigenvalues and eigenvectors feature prominently in the analysis of linear transformations.
