On the Solution of Circulant Linear Systems
Copyright policy )On the Solution of Circulant Linear Systems
The paper presents efficient methods for the solution of linear systems having circulant (banded circulant, block circulant) coefficient matrices. The proposed methods are more efficient than Toeplitz type methods and are based on the fast Fourier transform as well as the circulant factorization of ''banded'' circulant matrices.
