constrained column approximate library for sparse matrices

Suitesparse is a collection of libraries for computations involving sparse matrices.

The CCOLAMD library implements the "Constrained COLumn Approximate Minimum Degree ordering" algorithm. It 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.
