Webwe find the eigenvalues of a matrix by computing the characteristic polynomial;
What is the characteristic.
Set up the characteristic equation, using |a − λi| = 0.
Our task is to find the eigenvalues λ, and eigenvectors v, such that:
We are looking for scalar values λ.
Webto determine/find the eigenvalues of a matrix, calculate the roots of its characteristic polynomial.
