Class Dlasq6

    java.lang.Object
      org.netlib.lapack.Dlasq6

    public class Dlasq6

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
     *  =======
     *
     *  DLASQ6 computes one dqd (shift equal to zero) transform in
     *  ping-pong form, with protection against underflow and overflow.
     *
     *  Arguments
     *  =========
     *
     *  I0    (input) INTEGER
     *        First index.
     *
     *  N0    (input) INTEGER
     *        Last index.
     *
     *  Z     (input) DOUBLE PRECISION array, dimension ( 4*N )
     *        Z holds the qd array. EMIN is stored in Z(4*N0) to avoid
     *        an extra argument.
     *
     *  PP    (input) INTEGER
     *        PP=0 for ping, PP=1 for pong.
     *
     *  DMIN  (output) DOUBLE PRECISION
     *        Minimum value of d.
     *
     *  DMIN1 (output) DOUBLE PRECISION
     *        Minimum value of d, excluding D( N0 ).
     *
     *  DMIN2 (output) DOUBLE PRECISION
     *        Minimum value of d, excluding D( N0 ) and D( N0-1 ).
     *
     *  DN    (output) DOUBLE PRECISION
     *        d(N0), the last value of d.
     *
     *  DNM1  (output) DOUBLE PRECISION
     *        d(N0-1).
     *
     *  DNM2  (output) DOUBLE PRECISION
     *        d(N0-2).
