UDF(User-Defined Functions)是指在Excel中使用自定义函数。这些函数可以执行各种计算和操作,并将结果返回到工作表中。UDF可以使用VBA编写,也可以使用其他编程语言编写,并通过Excel的DLL接口进行调用。 例如,我们可以编写一个UDF来计算两个数字的平均值: 代码语言:vb 复制 Function Average(x As Double, y As Double...

一、自定义函数(User-Defined Function) 自定义函数是一种由用户编写的Excel函数,可以扩展Excel原有的函数库,实现特定功能的计算。以下是使用VBA编写自定义函数的步骤: 1.打开Excel并按下Alt + F11打开VBA编辑器。 2.在VBA编辑器中,选择“插入”>“模块”,新建一个模块。

End Function ``` 在这个示例中,我们定义了一个名为MyFunction的函数,接受两个整数型参数并返回它们的和。函数的返回值通过赋值给与函数同名的变量来实现。 二、使用函数的参数 在用户定义函数中,我们可以使用各种参数来定制函数的功能。VBA中的参数可以分为两类:必需参数和可选参数。必需参数是指在调用函数时必须...
在Excel中,UDF(User-Defined Function,用户自定义函数)是一种自定义的函数,可以通过VBA编程语言来创建。然而,并非所有的公共函数都可以作为UDF正常工作。 公共函数在Excel中是一种内置的函数,可以直接在单元格中使用,而无需通过VBA编程。这些公共函数包括SUM、AVERAGE、MAX、MIN等常见的数学和统计函数,以及IF、VLOOKUP...
6. Use the function (Appears in the Paste Function dialog box (press Shift+F3), under the "User Defined" category). If you want to use a UDF in more than one workbook, you can save your functions in your own custom add-in. Simply save the Excel file that contains your VBA functions...
Before I go over the step-by-step instructions for creating custom functions in Excel, let’s talk about user-defined functions. As the name suggests, it’s a custom function that you create using VBA to extend Excel’s capabilities beyond the built-in options. Let’s say you want to ex...
To create a custom function, we need to write a code for our functions' working, called “UDF.” The custom functions are user-defined in Excel, so you need to know VBA coding thoroughly to create these functions. You are free to use this image on your website, templates, etc..Please...
User-defined functions. The following code example shows a VBA user-defined function that uses the fact that the index to a collection must be unique. For an explanation of some techniques that are used, see the section about user-defined functions in the "Using functions efficiently" sec...
