Efficient computation of shifted linear systems of equations with application to PDEs

Efficient computation of shifted linear systems of equations with application to PDEs

Thesis (MSc)--Stellenbosch University, 2011. === ENGLISH ABSTRACT: In several numerical approaches to PDEs shifted linear systems of the form (zI - A)x = b, need to be solved for several values of the complex scalar z. Often, these linear systems are large and sparse. This thesis investigates effic...
