As shipped in IRIX 6.5.7. Unchanged since IRIX 6.5.

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( * )

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.
