Updating QR factorization technique for solution of saddle point problems

Updating QR factorization technique for solution of saddle point problems

We consider saddle point problem and proposed an updating $ QR $ factorization technique for its solution. In this approach, instead of working with large system which may have a number of complexities such as memory consumption and storage requirements, we computed $ QR $ factorization of matrix $...
