Abstract
- SUMMARY Strang's proposal to use a circulant preconditioner for linear systems of equations with a Hermitian positive definite Toeplitz matrix has given rise to considerable research on circulant preconditioners. This paper presents an {eiφ}-circulant Strang-type preconditioner. Copyright © 2011 John Wiley & Sons, Ltd.
