在程序设计语言里，用二维数组来保存矩阵的值。
一维列矩阵，就是由：若干行、一列组成的二维数组。
一维行矩阵，就是由：一行、若干列组成的二维数组。
比如一维列矩阵，的输入：
dim a(10,1) as integer '10行，1列
dim i as integer
for i = 1 to 10
a(i,1) = inputbox("")
next i
要实现什么样的功能呢?矩阵就是二维表吧,在.Net中有许多方法可以实现二维表,根据不同的需求选择适合的方法,你应该详细一点说明
Dim a(6, 6) As Integer, i As Integer, ii As Integer
Private Sub Command1_Click()
For i = 1 To 6
For ii = 1 To 4
a(i, ii) = Int(Rnd * 90 + 10)
Next ii
Next i
For i = 1 To 6
For ii = 1 To 4
Picture1.Print a(i, ii);
Next ii
Picture1.Print ""
Next i
End Sub
Private Sub Command2_Click()
For ii = 1 To 4
For i = 1 To 6
Picture2.Print a(i, ii);
Next i
Picture2.Print
Next ii
End Sub
