VB.Net矩阵求逆，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
Function Rect_yu(A As Array,L As Integer,C As Array) As Single '矩阵求逆
Dim T0 As Single
Dim T1 As Single
Dim T2 As Single
Dim T3 As Single
Dim B(0,0) As Single
Dim Num As Single
Dim Chay As Integer
Dim Chax As Integer
Chay = 0
Chax = 0
ReDim B(L - 1,L - 1)
Num = 0
Dim add As Double
add = 1 / Rect(A,L)
For T0 = 0 To L
For T3 = 0 To L
For T1 = 0 To L - 1
If T1 < T0 Then
Chax = 0
Else
Chax = 1
End If
For T2 = 0 To L - 1
If T2 < T3 Then
Chay = 0
Else
Chay = 1
End If
B(T1,T2) = A(T1 + Chax,T2 + Chay)
Next T2
Next T1
Rect(B,L - 1) '调用求行列式值
C(T3,T0) = Rect(B,L - 1) * add * ((-1) ^ (T0 + T3))
Next T3
Next T0
End Function
