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.
