Representations And Expansionsof Weighted Pseudoinverse Matrices, iterative Methods, And Problem regularization. i. Positive Definite Weights

摘要

The paper reviews studies on the representations and expansions of weighted pseudoinverse matrices with positive definite weights and on iterative methods and regularized problems for calculation of weighted pseudoinverse matrices and weighted normal pseudosolutions. The use of these methods to solve constrained least-squares problems is examined.
