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 is INTEGER
          The number of elements in the vector 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.
