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

Function/Subroutine Documentation

  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.
