IZMAX1 finds the index of the first vector element of maximum absolute value.

Function/Subroutine Documentation

  integer function izmax1 (integer N, complex*16, dimension(*) ZX, integer INCX)

IZMAX1 finds the index of the first vector element of maximum absolute value.

Purpose:

     IZMAX1 finds the index of the first vector element of 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 ZX.

    ZX

              ZX is COMPLEX*16 array, dimension (N)
              The vector ZX. The IZMAX1 function returns the index of its first
              element of maximum absolute value.

    INCX

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