- function p = symrcm(S)
- %SYMRCM Reverse Cuthill-McKee ordering.
- % p = SYMRCM(S) returns a permutation p such that S(p,p)
- % tends to have smaller profile than S. This is a
- % good preordering for LU or Cholesky factorization
- % of matrices that come from "long, skinny" problems.
- % It works for both symmetric and asymmetric S.
