| Outline of Final Research Achievements |
The purpose of this research is to create a framework of robust matrix factorization algorithms in numerical linear algebra. Since scientific computing is based on numerical linear algebra, development of such algorithms is very important. For this purpose, it was necessary to create a common framework for algorithms rather than considering details of individual algorithms. We succeeded in developing a robust factorization algorithm for real symmetric matrices. Moreover, we proposed robust numerical methods for eigenvalue problems and singular value problems.
