Class SLACON

    java.lang.Object
      org.netlib.lapack.SLACON

    public class SLACON

extends java.lang.Object

    SLACON is a simplified interface to the JLAPACK routine slacon.
    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
     *  =======
     *
     *  SLACON estimates the 1-norm of a square, real matrix A.
     *  Reverse communication is used for evaluating matrix-vector products.

     *
     *  Arguments
     *  =========
     *
     *  N      (input) INTEGER
     *         The order of the matrix.  N >= 1.
     *
     *  V      (workspace) REAL array, dimension (N)
     *         On the final return, V = A*W,  where  EST = norm(V)/norm(W)
     *         (W is not returned).
     *
     *  X      (input/output) REAL array, dimension (N)
     *         On an intermediate return, X should be overwritten by
     *               A * X,   if KASE=1,
     *               A' * X,  if KASE=2,
     *         and SLACON must be re-called with all the other parameters
     *         unchanged.
     *
     *  ISGN   (workspace) INTEGER array, dimension (N)
     *
     *  EST    (input/output) REAL
     *         On entry with KASE = 1 or 2 and JUMP = 3, EST should be
     *         unchanged from the previous call to SLACON.
     *         On exit, EST is an estimate (a lower bound) for norm(A).
     *
     *  KASE   (input/output) INTEGER
     *         On the initial call to SLACON, KASE should be 0.
     *         On an intermediate return, KASE will be 1 or 2, indicating
     *         whether X should be overwritten by A * X  or A' * X.
     *         On the final return from SLACON, KASE will again be 0.
