What is a User-defined function? A user defined function is a function that is declared by user, which means you can declare a function with any name for a specific task: Note:Pre-defined function: A function that is already present in the C library are known as predefined functions such...
C allows you to define functions according to your need. These functions are known as user-defined functions. For example: Suppose, you need to create a circle and color it depending upon the radius and color. You can create two functions to solve this problem: createCircle()function color(...

Like functions in programming languages, SQL Server user-defined functions are routines that accept parameters, perform an action, such as a complex calculation, and return the result of that action as a value. The return value can either be a single scalar value or a result set. Benefits of...
Use blocks from the User-Defined Functions library to extend Simulink® modeling functionality by creating new types of blocks. You can implement block algorithms using MATLAB®, C/C++, and Fortran® code.Blocks C Caller Integrate C code in Simulink C Function Integrate and call external C/...
To see all of these examples in action, grab a sample workbook here: file download Register a User Defined Function with Insert Function Registering a UDF will allow you to add a description to appear in the Insert Function dialog box and categorize it with the other native Excel functions. ...
User Defined Functions Introduction Pig provides extensive support for user defined functions (UDFs) as a way to specify custom processing. Pig UDFs can currently be implemented in three languages: Java, Python, JavaScript and Ruby. The most extensive support is provided for Java functions. You ...

在数据库对象“User Defined Functions” 上单击右键,从开始菜单中选择“New User Defined Function” 选项,就会出现如图13-4 所示的定义用户自定义函数属性对话框。可以在其中指定要定义的函数的名称,并编辑函数的脚本。单击“OK”按钮,则添加用户自定义函数对象到数据库中。
The next set of examples assume that you already have a container variable defined. To start, define the JavaScript function for the UDF in a string variable. C# stringudf =@"function addTax(preTax) { return preTax * 1.15; }";
