GAMS Module DSBEVD.C in CLAPACK


DSBEVD.C

 
Computes all eigenvalues and, optionally, eigenvectors of a real symmetric band
matrix. If eigenvectors are desired, an divide and conquer algorithm is used. [C
version of LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D4a1 . Real symmetric matrix eigenvalue problems
            D4a6 . Banded matrix eigenvalue problems
 
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 dsbevd_(char *jobz, char *uplo, integer *n, integer *kd,
           doublereal *ab, in teger *ldab, doublereal *w, doublereal *z,
           integer * ldz, doublereal *work, int eger *lwork, integer *iwork,
           integer * liwork, integer *info)

Sites    : (1) NETLIB
 

Implementation of DSBEVD.C from CLAPACK on NETLIB

 
NETLIB:    Public access repository, The University of Tennessee at
           Knoxville and Bell Laboratories
 
Precision: Double. (Single: SSBEVD.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.
 
   Access       : The entire package can be retrieved by anonymous ftp from
                  ftp.netlib.org.
   Source       : echo 'send only dsbevd.c from clapack/double' | mail
