大家在工作过程中，可能会遇到需要模糊匹配字符串的情况；
比如需要把简写疾病名称和一些已知疾病的名称进行匹配。
珂珂帮大家整理了一个匹配函数matchName，可以直接复制到工作表的模块中使用哦。
用法：第一个参数是匹配对象，第二个是匹配列表
结果：
代码如下， 匹配度计算参考这个博客
Public Function matchName(Target As String, TargetRange As Range) As String
On Error Resume Next
Dim tr As Variant, i As Integer, Temp_value As Double, Temp_result As String, final_value As Double
tr = TargetRange.Value
Temp_result = tr(1, 1)
For i = 1 To UBound(tr, 1)
Temp_value = sim(tr(i, 1), Target)
If Temp_value > final_value Then
final_value = Temp_value
Temp_result = tr(i, 1)
End If
Next i
matchName = Temp_result
End Function
Private Function min(one As Integer, two As Integer, three As Integer)
min = one
If (two < min) Then
min = two
End If
If (three < min) Then
min = three
End If
End Function
Private Function ld(str1 As String, str2 As String)
Dim N, m, i, j As Integer
Dim ch1, ch2 As String
N = Len(str1)
m = Len(str2)
Dim temp As Integer
If (N = 0) Then
ld = m
End If
If (m = 0) Then
ld = N
End If
Dim d As Variant
ReDim d(N + 1, m + 1) As Variant
For i = 0 To N
d(i, 0) = i
Next i
For j = 0 To m
d(0, j) = j
Next j
For i = 1 To N
ch1 = Mid(str1, i, 1)
For j = 1 To m
ch2 = Mid(str2, j, 1)
If (ch1 = ch2) Then
temp = 0
Else
temp = 1
End If
d(i, j) = min(d(i - 1, j) + 1, d(i, j - 1) + 1, d(i - 1, j - 1) + temp)
Next j
Next i
ld = d(N, m)
End Function
Public Function sim(ByVal str1 As String, ByVal str2 As String)
Dim ldint As Integer
ldint = ld(str1, str2)
Dim strlen As Integer
If (Len(str1) >= Len(str2)) Then
strlen = Len(str1)
Else
strlen = Len(str2)
End If
If strlen = 0 Then sim = 0 Else sim = 1 - ldint / strlen
End Function
