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.
Parameters:
[in]N
          N is INTEGER
          The number of elements in the vector CX.
[in]CX
          CX is COMPLEX array, dimension (N)
          The vector whose elements will be summed.
[in]INCX
          INCX is INTEGER
          The spacing between successive values of CX.  INCX >= 1.
