AMDBAR

 
Approximate minimum degree ordering for symmetric sparse matrices. Uses an
upper bound on the external degree to select pivots.
 
Classes  :  D2e . Operations associated with the solution of systems of linear
                equations, including matrix inverses, and LU and related
                factorizations (e.g., matrix reorderings)
 
Type     : Fortran subroutine in AMD package.
Access   : Some uses prohibited. Portable.
Precision: Single.
 
Usage    : CALL AMDBAR (N, PE, IW, LEN, IWLEN, PFREE, NV, NEXT, LAST, HEAD, ELEN,
           DEGREE, NCMPA, W, IOVFLO)
 
Details  : Readme Source
Sites    : (1) NETLIB
