define a function in matlab in matlab

main.m
        1. Create a new text file with a ".m" extension to define the function. The name of the file should match the name of the function, e.g. "myFunction.m".
        
        2. In the text file, start the first line with the word "function" followed by the output arguments in square brackets, e.g. "function [out1, out2] = myFunction(in1, in2)".
        
        3. On the next line, write a comment that briefly describes what the function does.
        
        4. On subsequent lines, write the code for the function, using the input arguments and any necessary local variables.
        
        5. End the function with the "end" keyword.
        
        Here's an example function definition that takes two input arguments and returns their sum:
        
        ```
        function [sum] = mySum(a,b)
        % Returns the sum of two numbers
          sum = a + b;
        end
        ```
