I need help in this problem ( I need MATLAB code not mathematical answer ) ONLY MATLAB CODE

For this homework assignment, you will create one script m-file that contains three code sections and two function m-files. The first code section of the script is for Problem 3.1 of the textbook, the second code section is for Problem 3.3, and the third code section is for Problem 3.15. You will create a function for Problem 3.1 and a different function for Problem 3.15. You will publish the script m-file. You will submit the PDF file that is created in the publishing process. Problem 3.15 You will create a function to help solve this problem. Don't forget to put a type command in your script. 3.15 Find the first few values of the response, iteratively, of the initially relaxed system governed by the difference equation y(n) = *(n) + y(n-1) with the following input. Is the response bounded? Is the system stable? (a)
