GAMS Module DCGC in LINALG


DCGC

 
Solves a symmetric positive definite linear system of equations using a
preconditioned conjugate gradient algorithm. The matrix structure as well as
basic operations on that structure (e.g. matrix-vector multiply) can be defined
by the user. (Developed by Mark Seager, Lawrence Livermore National
Laboratory.).
 
Classes  :  D2b1b . Solution of systems of linear equations, including matrix
                  inverses, and LU and related factorizations (real
                  symmetric positive definite matrices)
            D2b4 .  Solution of systems of linear equations, including matrix
                  inverses, and LU and related factorizations (real
                  symmetric sparse matrices)
 
Type     : C software in LINALG collection.
Access   : Some uses prohibited. Portable.
Precision: Double.
 
Details  : Fullsource
Sites    : (1) NETLIB
 

Implementation of DCGC from LINALG on NETLIB

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