"WebOne such method is based on the fact that the leading principal minors, det (Ar - ABr), r = 1, , n, form a Sturm sequence. Specific eigenvalues can therefore be isolated by the bisection method, exactly as in the classical Givens' method for tridiagonal matrices [6]. These minors can be determined reasonably " - Bisection eigenvalue algorithm
