Functions let you do a specific task. User defined functions are the functions created by the users according to their needs. This article explains how the user defined function in MATLAB is created.

Syntax : function [a1,…,an] = func(x1,…,xm)
func is the function name
a1,…,an are outputs
x1,…,xm are inputs
Function name is required, whereas input and output arguments are optional.

For making a user defined function in MATLAB, go to Home -> New -> Function. The function template appears as-

function [outputArg1,outputArg2] = untitled(inputArg1,inputArg2)      % UNTITLED Summary of this function goes here      % Detailed explanation goes here      outputArg1 = inputArg1;      outputArg2 = inputArg2;  end

Change the function name and save the file with the changes made. Save the file either in the current folder or in a folder on the MATLAB search path. The name of the function and the file should be same. For example, to create a function for calculating factorial, the code is:

   function f = fact(n) 
    f = 1; 
    i = 1; 
    while i <= n 
        f = f * i; 
        i = i + 1; 
    end
end
 
  

Save it and it can be run from the command window. The value of the fact() function returned, can also be stored in a variable. Code output for different values of n being passed :
