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.
