How do I make a master script that can call other scripts?

How would I go about doing this? I have a hw assignment with 3 different questions. I want to make a different script for each one, then make a master script that calls each one.

In your main script write

script1  % will run script1
script2  % will run script2
script3

master_script.m

function1();
function2();
function3();

end of master_script.m

function1(); %implements the logic for question1

function2(); %implements the logic for question2

function3(); %implements the logic for question3

Imagine you have the following 3 different .m files

function y=master(a,b)
y=y1(a)+y2(b);

function y=y2(b)
y=2*b;

function y=y1(a);
y=2*a;

When you write this in the command window

>> y=master(1,1)

y =

       4
