Question

我有一个很长的excel文件，其中包含从网站收集的数字。由于来自源的错误，不到1％的单元格包含零。因此，我想找到更新这些单元格并用最近的值插值它们。零单元的长度是单个时间，因此我可以简单地取最接近的非零值的平均值。但是，有些地方它比一个长，所以我需要使用线性插值。

这是一个非常通用的脚本，可能会做类似的事情。它仅在正值和十行上进行测试，因此您肯定需要将其调整到许多极端情况 - 但它应该指向正确的方向：

Sub Interpolate()
    Dim valueToTop As Integer

    For Row = 1 To 10
        valueToTop = -1
        valueToBottom = -1

        If Cells(Row, 1).Value = 0 Then
            RowToTop = Row - 1
            Do While RowToTop > 0
                If Cells(RowToTop, 1).Value > 0 Then
                    valueToTop = Cells(RowToTop, 1)
                    Exit Do
                End If
                RowToTop = RowToTop - 1
            Loop
            Debug.Print valueToTop
            Debug.Print RowToTop


            RowToBottom = Row + 1
            Do While RowToBottom > 0
                If Cells(RowToBottom, 1).Value > 0 Then
                    valueToBottom = Cells(RowToBottom, 1)
                    Exit Do
                End If
                RowToBottom = RowToBottom + 1
            Loop
            Debug.Print valueToBottom
            Debug.Print RowToBottom

            Cells(Row, 2).Value = valueToTop + (Row - RowToTop) * (valueToBottom - valueToTop) / (RowToBottom - RowToTop)


        End If



    Next Row
End Sub
