NAME
     izmax1 - find the index of the element whose real  part  has
     maximum absolute value

SYNOPSIS
     INTEGER FUNCTION IZMAX1( N, CX, INCX )

     INTEGER INCX, N

     COMPLEX*16 CX( * )



     #include <sunperf.h>

     int izmax1(int n, doublecomplex *cx, int *incx) ;

PURPOSE
     IZMAX1 finds the index of the element whose  real  part  has
     maximum absolute value.

     Based on IZAMAX from Level 1 BLAS.
     The change is to use the 'genuine' absolute value.

ARGUMENTS
     N         (input) INTEGER
               The number of elements in the vector CX.

     CX        (input) COMPLEX*16 array, dimension (N)
               The vector whose elements will be summed.

     INCX      (input) INTEGER
               The spacing between successive values of CX.  INCX
               >= 1.
