  • Abstract
    In calculating the coefficients of the characteristic polynomial of a square matrix A, the algorithm due to Leverrier is often used. However, due to numerical errors, this algorithm is not reliable when the dimension of A increases. A modification of this algorithm which increases the accuracy of the algorithm considerably will be proposed.
