Abstract:

The most common solution technique is subspace iteration, a combination of inverse iteration and the Rayleigh-Ritz procedure. Some difficulties of this method are mentioned as well as ways to avoid them by means of spectral transformations. This permits use of the Lanczos algorithm and yields significant reductions in cost. This paper evolved from an invited talk at the 2nd International Congress on Numerical Methods in Engineering GAMNI 2 at the Ecole Centrale de Paris in December 1980. Author
