WebJan 7, 2013 · 1)Your symmetric/hermitian Matrix H has a spectrum with positive and negative eigenvalues. Assume you can calculate the eigenvalue with maximum absolute value ω using power method. 2)Shift the matrix by a constant λ to target the part of the spectrum that you are interested H − λ I. Webthat the trace of the matrix is the sum of the eigenvalues. For example, the matrix " 6 7 2 11 # has the eigenvalue 13 and because the sum of the eigenvalues is 18 a second eigenvalue 5. A matrix with nonnegative entries for which the sum of the columns entries add up to 1 is called a Markov matrix. Markov Matrices have an eigenvalue 1. Proof.
