A Stable Algorithm to Compute Projecton PWA

摘要：

The perturbation bound of the projection PWA = (WA)(WA)+ is studied at fast, where both the matrices A and W are given with W positive diagonal and severely stiff. Then a stalbe algorithm to compute PWA is presented based on the row block column pivoting and row interchanging Householder QRD,the given example illustrates the given algorithm is numerical stable.
