Class Slarfg

      org.netlib.lapack.Slarfg

    public class Slarfg

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
     *  =======
     *
     *  SLARFG generates a real elementary reflector H of order n, such
     *  that
     *
     *        H * ( alpha ) = ( beta ),   H' * H = I.
     *            (   x   )   (   0  )
     *
     *  where alpha and beta are scalars, and x is an (n-1)-element real
     *  vector. H is represented in the form
     *
     *        H = I - tau * ( 1 ) * ( 1 v' ) ,
     *                      ( v )
     *
     *  where tau is a real scalar and v is a real (n-1)-element
     *  vector.
     *
     *  If the elements of x are all zero, then tau = 0 and H is taken to be

     *  the unit matrix.
     *
     *  Otherwise  1 <= tau <= 2.
     *
     *  Arguments
     *  =========
     *
     *  N       (input) INTEGER
     *          The order of the elementary reflector.
     *
     *  ALPHA   (input/output) REAL
     *          On entry, the value alpha.
     *          On exit, it is overwritten with the value beta.
     *
     *  X       (input/output) REAL array, dimension
     *                         (1+(N-2)*abs(INCX))
     *          On entry, the vector x.
     *          On exit, it is overwritten with the vector v.
     *
     *  INCX    (input) INTEGER
     *          The increment between elements of X. INCX > 0.
     *
     *  TAU     (output) REAL
     *          The value tau.
     *
