Diary Files: Before doing this assignment, please read the document Notes on Matlab Assignments (available from the course web page). It describes how to record the results of your Matlab session in a diary le, and then how to edit this le to create your Lab report.

IMPORTANT: The printed report that you hand in for grading must include both the Matlab commands that you typed at the prompt, and the output calculated by the Matlab program. This assignment is for a mathematics course, not a computer science course; the point of many of the calculations is to illustrate the mathematical concepts involved in linear algebra. In general, you should type the answers to the questions in your diary le at the time the computation related to each question is made. Do not wait until you have completed all the calculations.

Before beginning work on the Lab questions you should copy these codes to your workspace. Script Files: When you need to write a script le for this lab and subsequent labs, use the following procedure: Start Matlab and click on File, then New. Move the pointer to the right and click on m-Files. This will open the Matlab Editor/Debugger Window. Type the script commands in this window, then click on File in the Editor/Debugger toolbar and save your script on in your directory. After you have created and saved an m- le, you must set the Path so that Matlab can nd this le. Click on File and then Set Path and follow the directions to add your directory to the list of path names.

Script Files for this Lab: Use the text editor inMatlab to create the followingMatlab function m- les:

(a) Create a function m- file with the commands

function v = rvect(m)

v = fix(10*rand(m,1));
