Abstract: A number of localization regions that can be found by rational algorithms are indicated for the eigenvalues of a normal matrix. Rational algorithms are finite procedures using arithmetic operations only.
Key words: normal matrix, Toeplitz decomposition, linear fractional function, rational algorithm, inertia indices of a Hermitian matrix, localization regions for the eigenvalues.
