Preconditioning for Finger Pattern Matrices Arising from Wavelet Discretisations of Boundary Integral Equations
Stuart Collin Hawkins, Ke Chen · Kluwer Academic Publishers eBooks · 2006
A new preconditioning strategy is introduced for finger pattern matrices arising from the application of the discrete wavelet transform to discretisations of BIEs. The new strategy is compared against some existing preconditioning strategies and its advantage is demonstrated for low bandwidth preconditioners, and for problems witho diagonal features.
