ICMAX1 finds the index of the first vector element of maximum absolute value.

Function/Subroutine Documentation

  integer function icmax1 (integer n, complex, dimension(*) cx, integer incx)

ICMAX1 finds the index of the first vector element of maximum absolute value.

Purpose:

    !>
    !> ICMAX1 finds the index of the first vector element of maximum absolute value.
    !>
    !> Based on ICAMAX 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 array, dimension (N)
    !>          The vector CX. The ICMAX1 function returns the index of its first
    !>          element of maximum absolute value.
    !>

    INCX

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