review text: Some higher-order convergent methods for computing square roots of nonsingular complex matrices are derived. These methods are globally convergent and are based on eigenvalue shifting and powering. It is shown that for each positive integer \(r\geq 2\), a convergent method of order \(r\) can be developed.
