Yousef Saad

Yousef Saad ( born 1950 ) is an Algerian- American mathematician who deals with numerical linear algebra. He is a professor at the University of Minnesota.

Saad studied at the University of Algiers mathematics with the completion in 1970 and 1974 ( Thèse de 3eme Cycle) and 1983 ( Doctorat d' Etat) at the University of Grenoble in Francoise Chatelin doctorate (method numeriques pour la resolution de problemes de grandes matriciels dimensions ). From 1981 to 1983 he was at Yale University, 1983/84 Professor at the University of Tizi Ouzou, Algeria and 1986-1988 Associate Professor at the University of Illinois at Urbana- Champaign. In 1990 he became a professor at the University of Minnesota.

In 1986, he led with Martin H. Schultz, the GMRES method, a, an iterative Krylov method for the solution of large systems of linear equations, which can also be non- symmetrical.
