Import colamd, needed for upcoming octave update. The COLAMD column approximate minimum degree ordering algorithm computes a permutation vector P such that the LU factorization of A (:,P) tends to be sparser than that of A. The Cholesky factorization of (A (:,P))'(A (:,P)) will also tend to be sparser than that of A'A. SYMAMD is a symmetric minimum degree ordering method based on COLAMD, available as a MATLAB-callable function. It constructs a matrix M such that M'*M has the same pattern as A, and then uses COLAMD to compute a column ordering of M. Colamd and symamd tend to be faster and generate better orderings than their MATLAB counterparts, colmmd and symmmd. 2010-05-11 13:11:32 -04:00			`@comment $OpenBSD: PFRAG.shared,v 1.1.1.1 2010/05/11 17:11:32 pirofti Exp $`
