Characteristic polynomial

It is possible to calculate the coefficients of the characteristic polynomial of a real or interval matrix using the procedures:

INTERVAL_VECTOR Poly_Characteristic(MATRIX &A)

In both cases the coefficients are returned as an interval vector which contains the coefficients of the polynomial by increasing order.
