GAMS Module SPPEQU.C in CLAPACK


SPPEQU.C

 
Computes row and column scalings to equilibrate a real symmetric positive
definite matrix in packed storage and reduce its condition number.
(Computational routine.). [C version of LAPACK routine, converted from Fortran
by f2c.].
 
Classes  :  D2b1b . Solution of systems of linear equations, including matrix
                  inverses, and LU and related factorizations (real
                  symmetric positive definite matrices)
 
Type     : C subroutine in CLAPACK package.
Access   : Public domain. Portable.
Precision: Single.
Note     : For best results, CLAPACK developers prefer that you download and
           install the entire CLAPACK library on your system. To do this, see the 
           netlib CLAPACK distribution for details.
 
Usage    : int sppequ_(char *uplo, integer *n, real *ap, real *s, real * scond,
           real *amax, integer *info)
 
Details  : Fullsource Readme Source Utilities
Sites    : (1) NETLIB
 

Implementation of SPPEQU.C from CLAPACK on NETLIB

 
NETLIB:    Public access repository, The University of Tennessee at
           Knoxville and Bell Laboratories
 
Precision: Single. (Double: DPPEQU.C)
Note     : For best results, CLAPACK developers prefer that you download and
           install the entire CLAPACK library on your system. To do this, see the 
           netlib CLAPACK distribution for details.
 
You may access components from NETLIB outside GAMS as follows.
