vb6.0调用matlab函数绘图的问题

哼歌而梦

用vb调用matlab函数，并在vb界面图片框中显示代码如下：

1. Dim Matlab As Object
   
2. Dim Result As String
   
3. Private Sub Command1_Click()
   
4. Cmd = Text1.Text
   
5. Result = Matlab.execute("Cmd")
   
6. Picture1.Picture = Clipboard.GetData()
   
7. End Sub
   
8. Private Sub exitCommand_Click()
   
9. End
   
10. End Sub
    
11. Private Sub Form_Load()
    
12. Set Matlab = CreateObject("Matlab.Application")
    
13. Matlab.Visible = False
    
14. End Sub

我在textbox中输入"surf(peaks)",然后开始绘图，结果picturebox中什么也没有，是怎么回事？

Matlab.execute "plot([-pi:0.1:pi],sin([-pi:0.1:pi]))"
就出窗口了。
