This port installs the module CCOLAMD of SuiteSparse.
|
|
|
|
The CCOLAMD 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. CSYMAMD is a symmetric minimum
|
|
degree ordering method based on CCOLAMD, also available as a MATLAB-callable
|
|
function. It constructs a matrix M such that M'*M has the same pattern as A, and
|
|
then uses CCOLAMD to compute a column ordering of M.
