How can I assign a specific item of an array to a specific item of another array?

I have the following code:

Dim arrInputData As Double() = New Double(intGlobalHistory) {}
Dim arrOutputData As Double() = New Double(0) {}

Dim arrInputArray As Double()() = New Double(intGlobalStepping)() {}
Dim arrOutputArray As Double()() = New Double(intGlobalStepping)() {}

For intStepping As Integer = 0 To intGlobalStepping
    For intHistory As Integer = (intGlobalHistory + 1) To 1 Step -1
        arrInputData(intHistory - 1) = dblSomeInputFactor + CDbl(intHistory)
    Next intHistory

    arrOutputData = New Double() {dblSomeOutputFactor + CDbl(intStepping)}

    arrInputArray(intStepping) = arrInputData
    arrOutputArray(intStepping) = arrOutputData
Next intStepping

However, when I assign a specific item in the arrInputArray to arrInputData:

    arrInputArray(intStepping) = arrInputData

all other items in the arrInputArray variable also change to reflect the new value in the arrInputData variable.

What am I doing wrong? I only want the specific item in arrInputArray changed, leaving all other items untouched.

Thanks!
