Arrays skalieren/interpolieren

[Bummi]

nur mal schnell hingeschludert

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TFarray=Array of Double;
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

Procedure Interpolate(src,dest:TFarray);
//20101127 by Thomas Wassermann
var
  i,a,b:Integer;
  vh,ivh:Double;
begin
  vh := high(src) / high(dest);
  for I := low(dest) to High(dest)  do
      begin
      a := Trunc(i * vh);
      ivh := (i*vh) - Trunc(i * vh);
      b := a + 1;
      dest[i]:=(src[a] * (1-ivh)) + (src[b] * ivh) ;
      end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
   a,b:TFarray;
   i:INteger;
begin
   SetLength(a,11);
   for I := 0 to High(a) do a[i]:=i;
   SetLength(b,21);
   Interpolate(a,b);
   Showmessage('a');// als Debuggerbrechpunkt
end;

end.
