Class STPCON

    java.lang.Object
      org.netlib.lapack.STPCON

    public class STPCON

extends java.lang.Object

    STPCON is a simplified interface to the JLAPACK routine stpcon.
    This interface converts Java-style 2D row-major arrays into
    the 1D column-major linearized arrays expected by the lower
    level JLAPACK routines.  Using this interface also allows you
    to omit offset and leading dimension arguments.  However, because
    of these conversions, these routines will be slower than the low
    level ones.  Following is the description from the original Fortran
    source.  Contact seymour@cs.utk.edu with any questions.

     *  Purpose
     *  =======
     *
     *  STPCON estimates the reciprocal of the condition number of a packed
     *  triangular matrix A, in either the 1-norm or the infinity-norm.
     *
     *  The norm of A is computed and an estimate is obtained for
     *  norm(inv(A)), then the reciprocal of the condition number is
     *  computed as
     *     RCOND = 1 / ( norm(A) * norm(inv(A)) ).
     *
     *  Arguments
     *  =========
     *
     *  NORM    (input) CHARACTER*1
     *          Specifies whether the 1-norm condition number or the
     *          infinity-norm condition number is required:
     *          = '1' or 'O':  1-norm;
     *          = 'I':         Infinity-norm.
     *
     *  UPLO    (input) CHARACTER*1
     *          = 'U':  A is upper triangular;
     *          = 'L':  A is lower triangular.
     *
     *  DIAG    (input) CHARACTER*1
     *          = 'N':  A is non-unit triangular;
     *          = 'U':  A is unit triangular.
     *
     *  N       (input) INTEGER
     *          The order of the matrix A.  N >= 0.
     *
     *  AP      (input) REAL array, dimension (N*(N+1)/2)
     *          The upper or lower triangular matrix A, packed columnwise in

     *          a linear array.  The j-th column of A is stored in the array

     *          AP as follows:
     *          if UPLO = 'U', AP(i + (j-1)*j/2) = A(i,j) for 1<=i<=j;
     *          if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = A(i,j) for j<=i<=n.
     *          If DIAG = 'U', the diagonal elements of A are not referenced

     *          and are assumed to be 1.
     *
     *  RCOND   (output) REAL
     *          The reciprocal of the condition number of the matrix A,
     *          computed as RCOND = 1/(norm(A) * norm(inv(A))).
     *
     *  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
     *
     *  =====================================================================
