ITERATIVE METHODS TO CALCULATE WEIGHTED PSEUDOINVERSES WITH MIXED WEIGHTS

摘要

The authors have obtained and analyzed the expansions of weighted pseudoinverses with mixed weights (one of the weight matrices is positive definite and the other is nonsingular indefinite) into matrix power series with positive exponents. Iterative methods for calculation of weighted pseudoinverces with mixed weights have been generated and investigated on the basis of the obtained expansions of weighted pseudoinverses. Different variants of weighted pseudoinverces with mixed nonsingular weights are analyzed and developed into matrix power series.
