WebFormal Definition of Eigen Vector. A nonzero vector that is mapped by a given linear transformation of a vector space onto a vector that is the product of a scalar multiplied by the original vector. Eigenvector of a square matrix is defined as a non-vector by which given matrix is multiplied, and is equal to a scalar multiple of that vector.
