ICMAX1 - find the index of the element whose real part has maximum absolute value

As shipped in IRIX 6.5. First release of IRIX 6.5.

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( * )

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.
