Class Sggbak

    java.lang.Object
      org.netlib.lapack.Sggbak

    public class Sggbak

extends java.lang.Object

    Following is the description from the original
    Fortran source.  For each array argument, the Java
    version will include an integer offset parameter, so
    the arguments may not match the description exactly.
    Contact seymour@cs.utk.edu with any questions.

     *     ..
     *
     *  Purpose
     *  =======
     *
     *  SGGBAK forms the right or left eigenvectors of a real generalized
     *  eigenvalue problem A*x = lambda*B*x, by backward transformation on
     *  the computed eigenvectors of the balanced pair of matrices output by

     *  SGGBAL.
     *
     *  Arguments
     *  =========
     *
     *  JOB     (input) CHARACTER*1
     *          Specifies the type of backward transformation required:
     *          = 'N':  do nothing, return immediately;
     *          = 'P':  do backward transformation for permutation only;
     *          = 'S':  do backward transformation for scaling only;
     *          = 'B':  do backward transformations for both permutation and

     *                  scaling.
     *          JOB must be the same as the argument JOB supplied to SGGBAL.

     *
     *  SIDE    (input) CHARACTER*1
     *          = 'R':  V contains right eigenvectors;
     *          = 'L':  V contains left eigenvectors.
     *
     *  N       (input) INTEGER
     *          The number of rows of the matrix V.  N >= 0.
     *
     *  ILO     (input) INTEGER
     *  IHI     (input) INTEGER
     *          The integers ILO and IHI determined by SGGBAL.
     *          1 <= ILO <= IHI <= N, if N > 0; ILO=1 and IHI=0, if N=0.
     *
     *  LSCALE  (input) REAL array, dimension (N)
     *          Details of the permutations and/or scaling factors applied
     *          to the left side of A and B, as returned by SGGBAL.
     *
     *  RSCALE  (input) REAL array, dimension (N)
     *          Details of the permutations and/or scaling factors applied
     *          to the right side of A and B, as returned by SGGBAL.
     *
     *  M       (input) INTEGER
     *          The number of columns of the matrix V.  M >= 0.
     *
     *  V       (input/output) REAL array, dimension (LDV,M)
     *          On entry, the matrix of right or left eigenvectors to be
     *          transformed, as returned by STGEVC.
     *          On exit, V is overwritten by the transformed eigenvectors.
     *
     *  LDV     (input) INTEGER
     *          The leading dimension of the matrix V. LDV >= max(1,N).
     *
     *  INFO    (output) INTEGER
     *          = 0:  successful exit.
     *          < 0:  if INFO = -i, the i-th argument had an illegal value.
     *
     *  Further Details
     *  ===============
     *
     *  See R.C. Ward, Balancing the generalized eigenvalue problem,
     *                 SIAM J. Sci. Stat. Comp. 2 (1981), 141-152.
