GAMS Module ZGELSX.C in CLAPACK


ZGELSX.C

 
Computes the minimum norm least squares solution to an over- or under-determined
system of linear equations A X=B, using a complete orthogonal factorization of A.
(Expert driver.). [C version of LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D9a1 . Least squares (L-2) solution of singular, overdetermined or
                 underdetermined systems of linear equations without
                 constraints
 
Type     : C subroutine in CLAPACK package.
Access   : Public domain. Portable.
Precision: Double.
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 zgelsx_(integer *m, integer *n, integer *nrhs, doublecomplex
           *a, integer *l da, doublecomplex *b, integer *ldb, integer *jpvt,
           doublereal *rcond, integer *rank, doublecomplex *work,
           doublereal *rwork, integer *info)

Implementation of ZGELSX.C from CLAPACK on NETLIB

 
NETLIB:    Public access repository, The University of Tennessee at
           Knoxville and Bell Laboratories
 
Precision: Double. (Single: CGELSX.C)
