Question

Dim chi As Variant和chi(1)是什么意思

Public Function GetAmericanDelta(CallPutFlag As String, s As Double, X As Double, r As Double, q As Double, sigma As Double, t As Double) As Double

Dim phi As Double, Sseed As Double, Sstar As Double, BSprice As Double, hAh As Double, lamda As Double, deltaBS As Double

Dim chi As Variant // 这里是个啥意思，相当于auto吗

If phi * (Sstar - s) > 0 Then chi（1） 是啥意思
GetAmericanDelta = deltaBS + (lamda / s / (1# - chi(1))
End If
End Function

Answer 1

outCode(0,0)就是这个数组的第一个元素。
与它对应的不是Arraylist,在java中引用数组元素的方法与VB一样，都是写outCode(0,0),如
outCode(0,0) = 3;
