If you develop a User Defined Function (UDF) you may need to make it Volatile (Application.Volatile(True)) to make it recalculate BUT: Application.Volatile makes your function ALWAYS recalculate each time Excel calculates, which can slow down calculation. ...
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...
For an excellent explanation of virtually everything you need to know to create your own Excel UDFs, see John Walkenbach's book, Excel 2002 Formulas. The book provides many good user defined function examples, so if you like to learn by example, it is a great resource....

虽然知道Microsoft Office Excel可以支持用VB语言来进行复杂的编程和自定义函数的编写,但是一直以来都没有这个需求。 这次遇到的问题是要根据一列数组计算出一个值,但计算过程又比较复杂,需要经过几步,如果不编程的话总要经过一些中间单元格来完成计算,但这又会使得整个表格变得很臃肿,并且不方便添加新列。
Both the VBA and C API support ways to inform Excel that a user-defined function (UDF) should be handled as volatile. By using VBA, the UDF is declared as volatile as follows. Visual Basic for Applications Function MyUDF(MakeMeVolatile As Boolean) As Double ' Good practice to call this...

You can make a user-defined function volatile by including Application.Volatile in the function code.Some of the built-in functions in Excel are obviously volatile: RAND(), NOW(), TODAY(). Others are less obviously volatile: OFFSET(), CELL(), INDIRECT(), INFO()....

User-Defined FunctionsAll user-defined functions in Excel 2007, regardless of the language and add-in method used to develop them, can now support the increased limits of Excel 2007, including the number of function arguments and the "Big Grid." Fully supporting the "Big Grid" may require ...
