问题
I am trying to move data from 2 Double Arrays to 2 different Double Arrays. I'm not sure what the size is going to be because I am taking a randomized sample out of the first arrays and putting it into the 2nd arrays.
When I add the ReDim Preserve line I get the Subscript Out of Range error.
Function CreateTrainingSet(TrainingPercent As Double, Inputs() As Double, Outputs() As Double)
' Create Randomized Training set data
Dim TrainingInputs() As Double, TrainingOutputs() As Double
Dim i As Integer, j As Integer, count As Integer
'ReDim TrainingInputs(UBound(Inputs, 1), UBound(Inputs, 2))
'ReDim TrainingOutputs(UBound(Outputs, 1), UBound(Outputs, 2))
count = 0
' Move TraningPercent % of data from Inputs and Outputs to TrainingInputs and TrainingOutputs
For i = LBound(Inputs, 1) To UBound(Inputs, 1)
Dim ran As Double
ran = Rnd()
If ran <= TrainingPercent Then
count = count + 1
For j = LBound(Inputs, 2) To UBound(Inputs, 2)
ReDim Preserve TrainingInputs(1 To count, 1 To UBound(Inputs, 2))
TrainingInputs(count, j) = Inputs(i, j)
Next j
For j = LBound(Outputs, 2) To UBound(Outputs, 2)
ReDim Preserve TrainingOutputs(1 To count, 1 To UBound(Outputs, 2))
TrainingOutputs(count, j) = Outputs(i, j)
Next j
End If
Next i
For i = LBound(TrainingInputs, 1) To UBound(TrainingInputs, 1)
For j = LBound(TrainingInputs, 2) To UBound(TrainingInputs, 2)
Cells(i, j + 10).Value = TrainingInputs(i, j)
Next j
Next i
End Function

To summarise the comments above into an answer:
- You can only redim the last dimension of a multi dimension array
Therefore in order to resize a multiple dimension array there are a couple of simple options:
- If only one dimension needs to be resized flip the loops and logic around so that the dimension to be resized becomes the last dimension
- If both dimensions must be resized use either an array of arrays or a collection of arrays and correct the loops as required
