CHAPTER Computing the Cholesky Factorization of Sparse Matrices In many support preconditioners the preconditioner is factored before the iterations begin
The Cholesky factorization of allows us to e64259ciently solve the correction equations Bz This chapter explains the principles behind the factorization of sparse symmetric positive de64257nite matrices 1 The Cholesky Factorization We 64257rst show
