Class Spbcon

      org.netlib.lapack.Spbcon

    public class Spbcon

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.

     *  Purpose
     *  =======
     *
     *  SPBCON estimates the reciprocal of the condition number (in the
     *  1-norm) of a real symmetric positive definite band matrix using the
     *  Cholesky factorization A = U**T*U or A = L*L**T computed by SPBTRF.
     *
     *  An estimate is obtained for norm(inv(A)), and the reciprocal of the
     *  condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))).
     *
     *  Arguments
     *  =========
     *
     *  UPLO    (input) CHARACTER*1
     *          = 'U':  Upper triangular factor stored in AB;
     *          = 'L':  Lower triangular factor stored in AB.
     *
     *  N       (input) INTEGER
     *          The order of the matrix A.  N >= 0.
     *
     *  KD      (input) INTEGER
     *          The number of superdiagonals of the matrix A if UPLO = 'U',
     *          or the number of subdiagonals if UPLO = 'L'.  KD >= 0.
     *
     *  AB      (input) REAL array, dimension (LDAB,N)
     *          The triangular factor U or L from the Cholesky factorization

     *          A = U**T*U or A = L*L**T of the band matrix A, stored in the

     *          first KD+1 rows of the array.  The j-th column of U or L is
     *          stored in the j-th column of the array AB as follows:
     *          if UPLO ='U', AB(kd+1+i-j,j) = U(i,j) for max(1,j-kd)<=i<=j;

     *          if UPLO ='L', AB(1+i-j,j)    = L(i,j) for j<=i<=min(n,j+kd).

     *
     *  LDAB    (input) INTEGER
     *          The leading dimension of the array AB.  LDAB >= KD+1.
     *
     *  ANORM   (input) REAL
     *          The 1-norm (or infinity-norm) of the symmetric band matrix A.
     *
     *  RCOND   (output) REAL
     *          The reciprocal of the condition number of the matrix A,
     *          computed as RCOND = 1/(ANORM * AINVNM), where AINVNM is an
     *          estimate of the 1-norm of inv(A) computed in this routine.
     *
     *  WORK    (workspace) REAL array, dimension (3*N)
     *
     *  IWORK   (workspace) INTEGER array, dimension (N)
     *
     *  INFO    (output) INTEGER
     *          = 0:  successful exit
     *          < 0:  if INFO = -i, the i-th argument had an illegal value
     *
     *  =====================================================================
