Two-dimensional arrays

1.

Summary: (1), Ii[x][y]: where x indicates which row, Y indicates which column

(2), dynamic non-matrix two-dimensional array ==> or less (or not) as well ...

2. Test code:

procedureTform1.button3click (sender:tobject);varII3:Array[0..1,0..2] ofInteger;beginMemo1.Lines.Add ("'); MEMO1.LINES.ADD ('A two-dimensional array of static matrices:'); MEMO1.LINES.ADD (IntToStr (Integer (@ii3 [0,0]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii3 [0][1]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii3 [0][2]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii3 [1][0]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii3 [1][1]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii3 [1][2])));End;procedureTform1.button4click (sender:tobject);varII4:Array  of Array  ofInteger;beginMemo1.Lines.Add ("'); MEMO1.LINES.ADD ('two-dimensional array of dynamic matrices:'); SetLength (Ii4,2,3); MEMO1.LINES.ADD (IntToStr (Integer (@ii4 [0,0]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii4 [0][1]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii4 [0][2]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii4 [1][0]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii4 [1][1]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii4 [1][2])));End;procedureTform1.button5click (sender:tobject);varII5:Array  of Array  ofInteger;beginMemo1.Lines.Add ("'); MEMO1.LINES.ADD ('Dynamic Non-matrix two-dimensional arrays:'); SetLength (Ii5,2); SetLength (ii5[0],3); MEMO1.LINES.ADD (IntToStr (Integer (@ii5 [0,0]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii5 [0][1]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii5 [0][2]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii5 [1][0]))); MEMO1.LINES.ADD ("'); SetLength (ii5[1],4); MEMO1.LINES.ADD (IntToStr (Integer (@ii5 [1][0]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii5 [1][1]))); MEMO1.LINES.ADD (IntToStr (Integer (@ii5 [1][2])));End;

2.1. Output:
