Description-en: column approximate minimum degree ordering library for sparse matrices
Suitesparse is a collection of libraries for computations involving
sparse matrices.
.
The COLAMD library implements the "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.
