integer function izmax1 (N, CX, INCX)

IZMAX1 finds the index of the vector element whose real part has maximum absolute value.

integer function izmax1 (integerN, complex*16, dimension( * )CX, integerINCX)

IZMAX1 finds the index of the vector element whose real part has maximum absolute value.

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.

Parameters:

N

          N is INTEGER
          The number of elements in the vector CX.

CX

          CX is COMPLEX*16 array, dimension (N)
          The vector whose elements will be summed.

INCX

          INCX is INTEGER
          The spacing between successive values of CX.  INCX >= 1.
