我有這個小組在循環中做2個基本計算,然後我有一個UDF(見下文)。函數調用時未被調用,並停止主宏
我的問題:當我運行Sub BSM_Table
它調用此行的功能:If Cells(i, 2) > 0 And Cells(i, 3) > 0 Then
和子站。
我想這是因爲這些單元格:Cells(i, 2)
和Cells(i, 3)
由函數使用,所以無論何時這些單元格更改該函數自動重新自行計算。
有沒有辦法在需要時調用函數只有?
Sub BSM_Table()
Dim i As Long
Dim LastRow As Long, LastRow2 As Long
Dim Firm_Value As Double, Face_Value As Double, Rate As Double, Volatility_value As Double, Time As Double
With Sheets("BlackScholeMerton")
LastRow = Sheets("BlackScholeMerton").Range("B42:B" & Rows.Count).End(xlDown).Row
For i = 42 To LastRow
' If Cells(i, 2) > 0 And Cells(i, 3) > 0 Then
Range("E" & i).Value = Range("B" & i).Value + Range("C" & i).Value
x = Cells(i, 4) * Cells(i, 2)
y = Cells(i, 5)
Cells(i, 6) = x/y
' End If
Next i
End sub
我的功能:
Function DefProb(Firm_Value As Double, Face_Value As Double, Rate As Double, Volatility_value As Double, Time As Double) As Double
Dim t1 As Double, t2 As Double, t3 As Double
Dim d2 As Double, ta As Double, tb As Double
Dim V As Double, S As Double, x As Double
Dim r As Double, ti As Double
S = Firm_Value
x = Face_Value
r = Rate
V = Volatility_value
ti = Time
t1 = Log(S/x) + (r + V^2/2) * ti
t2 = V * Sqr(ti)
t3 = Log(S/x) + (r - V^2/2) * ti
d2 = t3/t2
DefProb = WorksheetFunction.NormSDist(-d2)
End Function
'Application.Calculation'有效。我沒有考慮這樣做。感謝您的快速回答 – manu
