Custom function blocks such as MATLAB Function, MATLAB System, Simulink Function, and Initialize Function 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 For...
Example: User-defined function Here is an example to add two integers. To perform this task, we have created an user-defined addNumbers(). #include <stdio.h> int addNumbers(int a, int b); // function prototype int main() { int n1,n2,sum; printf("Enters two numbers: "); scanf(...
CREATE TEMPORARY FUNCTION local-function-name AS 'package-name.function-name'; You can then use the UDF in your Hive query or transformation. For example, if the UDF returns a text string value you can use it as shown in the following code to replace the value in the specified column of...
The general format for a function header is: R← A FUNCTION B;VAR1;VAR2 or A FUNCTION B;VAR1;VAR2 depending on whether or not a result is returned. R, the result, A, the left argument, B, the right argument are all optional. Local names, if any, are listed after the function ...
