how do i make my code into a function in matlab

To create a function in matlab, you need to follow these steps:

1. Open a new file in matlab Editor.
2. In the first line, write the function declaration and name the file the same name as your function. The syntax is as follows:

main.m
function [outputArg1,outputArg2] = functionName(inputArg1,inputArg2)
    % function body
end
93 chars
4 lines

3. In the body of the function, write the code that you want to execute within the function.
4. Assign the output values to the variable names you specified in the function declaration.
5. Save the function with the .m extension.

Here is an example code for a simple function which takes two inputs and returns their sum:

main.m
function [sum] = addition(a,b)
    % This function takes two inputs and returns their sum
    sum = a + b;
end
111 chars
5 lines

You can then call the function by typing its name in the Matlab Command Window along with its input arguments separated by commas:

main.m
>> addition(2,3)
ans = 
    5
30 chars
4 lines

This will return the sum of 2 and 3, which is 5.
