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.
