Meanings

1. Given a square matrix A with eigenvector x and eigenvalue λ, and given the Identity matrix I of the same order (size) as A, an eigenpolynomial is the polynomial of λ that calculates the determinant of A - λI.
   • An important expression in the linear control theory is the eigenpolynomial of A. 2013, Vladimir P. Gerdt, Wolfram Koepf, Ernst W. Mayr, Computer Algebra in Scientific Computing, page 317:
