vb.net的矩阵乘法

问题描述

请尽快帮助我解决矩阵乘法的问题

please help me as early as possible to solve the problem of matrix multiplication

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
       ar1txt.Text = "2"
       ai1txt.Text = "3"
       ar2txt.Text = "4"
       ai2txt.Text = "5"
       ar3txt.Text = "6"
       ai3txt.Text = "7"
       ar4txt.Text = "8"
       ai4txt.Text = "9"


       br1txt.Text = "2"
       bi1txt.Text = "3"
       br2txt.Text = "4"
       bi2txt.Text = "5"
       br3txt.Text = "6"
       bi3txt.Text = "7"
       br4txt.Text = "8"
       bi4txt.Text = "9"


       Dim A(0 To 10, 0 To 10) As Double
       Dim B(0 To 10, 0 To 10) As Double
       Dim Product(0 To 10, 0 To 10) As Double
       Dim J As Integer
       Dim K As Integer
       Dim X As Integer
       For J = 0 To 10
           For K = 0 To 10
               Product(J, K) = A(J, X) * B(X, K)
               For X = 1 To 10
                   Product(J, K) = Product(J, K) + A(J, X) * B(X, K)
               Next X
           Next K
       Next J
       ans1txt.Text = Product(J, K)
       ans2txt.Text = Product(J, K)
       ans3txt.Text = Product(J, K)
       ans4txt.Text = Product(J, K)

   End Sub

这是我的矩阵乘法代码
但由于出现索引超出数组范围"而报错
请告诉我哪里出错了

this is my code for matrix multiplication
but getting error as "Index was outside the bounds of the array"
please tell me where its getting wrong
