public class DLADIV

extends Object

DLADIV is a simplified interface to the JLAPACK routine dladiv.
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
 *  =======
 *
 *  DLADIV performs complex division in  real arithmetic
 *
 *                        a + i*b
 *             p + i*q = ---------
 *                        c + i*d
 *
 *  The algorithm is due to Robert L. Smith and can be found
 *  in D. Knuth, The art of Computer Programming, Vol.2, p.195
 *
 *  Arguments
 *  =========
 *
 *  A       (input) DOUBLE PRECISION
 *  B       (input) DOUBLE PRECISION
 *  C       (input) DOUBLE PRECISION
 *  D       (input) DOUBLE PRECISION
 *          The scalars a, b, c, and d in the above expression.
 *
 *  P       (output) DOUBLE PRECISION
 *  Q       (output) DOUBLE PRECISION
 *          The scalars p and q in the above expression.
