GAMS Module 529 in TOMS


529

 
MC13D: a Fortran subroutine for finding symmetric permutations to block
triangular form. That is, given the column numbers of the nonzeros in each row of a
sparse matrix, this subroutine finds a symmetric permutation that makes the
matrix block lower triangular. (See I.S. Duff and J.K. Reid, ACM TOMS 4 (1978) pp.
189-192.).
 
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 software in TOMS collection.
Access   : Some uses prohibited. Portable.
Precision: Single.
 
Usage    : CALL MC13D(N, ICN, LICN, IP, LENR, IOR, IB, NUM, IW)
 
Details  : Fullsource
Sites    : (1) NETLIB
 

Implementation of 529 from TOMS on NETLIB

 
NETLIB:    Public access repository, The University of Tennessee at
           Knoxville and Bell Laboratories
 
Precision: Single.
 
You may access components from NETLIB outside GAMS as follows.
