The calculator below computes coefficients of a characteristic polynomial of a square matrix using the Faddeev—LeVerrier algorithm. You can find theory and formulas below the calculator. Given a square matrix A, we want to find a polynomial whose zeros are the eigenvalues of A. For a diagonal matrix A, the characteristic polynomial is easy to define: if the diagonal entries are a1, a2, a3, etc. For a general matrix A, one can proceed as follows. The coefficients can be found using the recursive Faddeev—LeVerrier algorithm first published in by Urbain Le Verrier, in present form redeveloped by Dmitry Konstantinovich Faddeev and others.

Do you want to learn how to find the characteristic polynomial? Keep reading, as we first recall what a characteristic polynomial is and then give the formulas as well as examples. In particular, there is a detailed explanation of how to find the characteristic polynomial of a 3x3 matrix. If you're working with matrices, you might also find our eigenvalue and eigenvector calculator useful. Hence, those polynomials coincide if n is even. If n is odd, you can go from one polynomial to the other by changing all their coefficients to opposite numbers i. However, as long as we are concerned with the roots i. As you now know what a characteristic polynomial is, why not look at some examples of how to find the characteristic polynomial? You don't need to be a math expert to use the characteristic polynomial calculator. Just follow steps below:. Let us take a look at an example. We will find the characteristic polynomial of the following matrix:.

The coefficients of the characteristic polynomial are determined recursively from the top down, by dint of the auxiliary matrices M 2 .
