Algorithm 887: CHOLMOD, Supernodal Sparse Cholesky Factorization and Update/Downdate


CHOLMOD is a set of routines for factorizing sparse symmetric positive definite matrices of the form <i>A</i> or <i>AA</i><sup>T</sup>, updating/downdating a sparse Cholesky factorization, solving linear systems, updating/downdating the solution to the triangular system <i>Lx</i>&thinsp;=&thinsp;<i>b</i>, and many other sparse matrix functions for both… (More)
