NAME
     icmax1 - find the index of the element whose real  part  has
     maximum absolute value

SYNOPSIS
     INTEGER FUNCTION ICMAX1( N, CX, INCX )

     INTEGER INCX, N

     COMPLEX CX( * )



     #include <sunperf.h>

     int icmax1(int n, complex *cx, int *incx) ;

PURPOSE
     ICMAX1 finds the index of the element whose  real  part  has
     maximum absolute value.

     Based on ICAMAX 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 array, dimension (N)
               The vector whose elements will be summed.

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