F11BFF

 
The third in a suite of three routines for the iterative solution of a real general
(nonsymmetric) system of simultaneous linear equations (Golub and Van Loan
[1]). F11BFF returns information about the computations during an iteration
and/or after this has been completed. The first routine of the suite, F11BDF, is a
set-up routine; the second routine, F11BEF is the iterative solver itself. .
 
Classes  :  D2a4 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (real
                 nonsymmetric sparse matrices)
 
Type     : Fortran subroutine in NAG library (F11 sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Double.
 
Usage    : CALL F11BFF(ITN, STPLHS, STPRHS, ANORM, SIGMAX, WORK, LWORK, IFAIL)
 
See also : F11BDF, F11BEF

Implementation of F11BFF from NAG on AIX

 
AIX:       IBM RS6000, National Institute of Standards and Technology (NIST),
           Gaithersburg, MD. Available to NIST staff.
 
Precision: Double.
 
Access available only to NIST staff on internal Unix systems. They may access this
package provided the /itl tree is cross-mounted.
