membuat program perkalian matriks dengan delphi

cuma mau ngeshare aja, gimana sih cara buat perkalian matriks di program delphi ..

unit tugas_perkalian;

interface

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

type
  TForm1 = class(TForm)
    Label1: TLabel;
    Label2: TLabel;
    Label3: TLabel;
    Label4: TLabel;
    Label5: TLabel;
    Edit1: TEdit;
    Edit2: TEdit;
    Edit3: TEdit;
    Edit4: TEdit;
    StringGrid2: TStringGrid;
    StringGrid3: TStringGrid;
    Button1: TButton;
    Button2: TButton;
    StringGrid1: TStringGrid;
    procedure Edit1Change(Sender: TObject);
    procedure Edit2Change(Sender: TObject);
    procedure Edit3Change(Sender: TObject);
    procedure Edit4Change(Sender: TObject);
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Edit1Change(Sender: TObject);
begin
stringgrid1.RowCount := strtoint (edit1.Text)
end;

procedure TForm1.Edit2Change(Sender: TObject);
begin
stringgrid1.ColCount := strtoint (edit2.Text)
end;

procedure TForm1.Edit3Change(Sender: TObject);
begin
stringgrid2.RowCount := strtoint (edit3.Text)
end;

procedure TForm1.Edit4Change(Sender: TObject);
begin
stringgrid2.colCount := strtoint (edit4.Text)
end;

procedure TForm1.Button1Click(Sender: TObject);
var c,i,j,k,m,n,o,p : integer;
begin
n := strtoint (edit1.Text);
m := strtoint (edit2.Text);
o := strtoint (edit3.Text);
p := strtoint (edit4.Text);
stringgrid1.RowCount := n;
stringgrid1.colCount := m;
stringgrid2.RowCount := o;
stringgrid2.colCount := p;
if m=o then k:=m;
for i:= 0 to n-1 do
for j := 0 to p-1 do
begin
c:= 0;
for k := 0 to m-1 do
c:= c + strtoint (stringgrid1.Cells[k,i]) * strtoint (stringgrid2.Cells[j,k]);
stringgrid3.Cells[j,i]:= inttostr (c);
end;
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
application.Terminate
end;

end.

hasil outputnya kaya gini ni

selamat mencoba guys :)
