WebOct 29, 2013 · @TylerJandreau The question is about computing eigenvalues accurately, and I infer that had MATLAB been accurate enough, it would suffice. It appears to be impossible to compute eigenvalues numerically for this type of matrix with the requested accuracy, so there's no reason not to be satisfied with MATLAB's answer. The most reliable and most widely used algorithm for computing eigenvalues is John G. F. Francis' QR algorithm, considered one of the top ten algorithms of 20th century. Any monic polynomial is the characteristic polynomial of its companion matrix. Therefore, a general algorithm for finding eigenvalues could also be used to find the roots of polynomials. The Abel–Ruffini theorem shows that any such algorithm for dimensions greater than 4 must either b…
