Abstract
The geometric mean of two matrices is considered from a computational viewpoint. Several numerical algorithms based on different properties and representations of the geometric mean are discussed and analyzed. It is shown that most of the algorithms can be classified in terms of the rational approximations of the inverse square root function. A review of relevant applications is given.File in questo prodotto:
