How can I call sub-functions in the Main function

So I have four functions and 3 of them are sub-functions and I am told that the 1 main function must call the other 3 functions in its execution I would please like to know how to call these sub-functions in my main code when I am using MATLAB grader

How do you define "sub-functions"? Are they just normal functions defined in 3 separate files?

[Thibedi Malotana]

Yes they are just 3 different functions in separate files

I haven't used MATLAB grader, but you should be able to call them like normal MATLAB functions.

function main % name of main function
    y = sub_fun1(x1, x2, x3) % name of a sub-function, x1 x2 x3 are input arguments
    % similar lines for sub_fun2 and sub_fun3
end

You can read following documentation to read about basics of function definition and call in MATLAB

I assume the 3 subfunction have been provided for you. They exist in the current folder. The instructor will have had to have provided you with information on what their inputs and outputs are. Call them like you would any other function: [outputs] = funcName(inputs);
