Bollettino dell'Unione Matematica Italiana

Similarity:

In this paper we consider the eigenvalue problem for positive definite symmetric matrices. Convergence properties for the zero shift $Q R$ method and the shift $L R$ Cholesky method both in restoring and in non restoring version are deduced from the convergence properties of triangular matrices sequences. For general matrices we obtain some results on the convergence speed of the Cholesky method as a function of the chosen shift. These results follow from the absolute convergence of numerical...

An Iterative Method for the Matrix Principal n-th Root

Lakić, Slobodan (1995)

Serdica Mathematical Journal

Similarity:

In this paper we give an iterative method to compute the principal n-th root and the principal inverse n-th root of a given matrix. As we shall show this method is locally convergent. This method is analyzed and its numerical stability is investigated.
