1This port installs the module COLAMD of SuiteSparse.

3The CCOLAMD column approximate minimum degree ordering algorithm computes a
4permutation vector P such that the LU factorization of A (:,P) tends to be
5sparser than that of A. The Cholesky factorization of (A (:,P))'*(A (:,P)) will
6also tend to be sparser than that of A'*A. CSYMAMD is a symmetric minimum degree
7ordering method based on CCOLAMD, also available as a MATLAB-callable function.
8It constructs a matrix M such that M'*M has the same pattern as A, and then uses
9CCOLAMD to compute a column ordering of M.
