public class Slasq6
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
 *  =======
 *
 *  SLASQ6 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) REAL 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) REAL
 *        Minimum value of d.
 *
 *  DMIN1 (output) REAL
 *        Minimum value of d, excluding D( N0 ).
 *
 *  DMIN2 (output) REAL
 *        Minimum value of d, excluding D( N0 ) and D( N0-1 ).
 *
 *  DN    (output) REAL
 *        d(N0), the last value of d.
 *
 *  DNM1  (output) REAL
 *        d(N0-1).
 *
 *  DNM2  (output) REAL
 *        d(N0-2).
