# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.
# Line up the first '|' above the ':' following the base package name, and
# the '|' on the right side marks the last column you can put a character in.
# You must make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':' except on otherwise blank lines.

colamd: COLAMD (sparse matrix ordering routines)
colamd:
colamd: The COLAMD column approximate minimum degree ordering algorithm
colamd: computes a permutation vector P such that the LU factorization of
colamd: A (:,P) tends to be sparser than that of A.  The Cholesky
colamd: factorization of (A (:,P))'*(A (:,P)) will also tend to be sparser
colamd: than that of A'*A.
