Title: SuiteSparse/User Guide for LDL, a concise sparse Cholesky package
Author: Timothy A. Davis
Abstract: The LDL software package is a set of short, concise routines for
factorizing symmetric positive-definite sparse matrices, with some
applicability to symmetric indefinite matrices. Its primary purpose is to
illustrate much of the basic theory of sparse matrix algorithms in as concise
a code as possible, including an elegant method of sparse symmetric
factorization that computes the factorization row-by-row but stores it
column-by-column. The entire symbolic and numeric factorization consists of
less than 50 lines of code. The package is written in C, and includes a MATLAB
interface.
