Policies
DMS Course Policies: All DMS students must familiarize themselves with, and adhere to, the Department of Mathematical Sciences Course Policies, in addition to official universitywide policies. DMS takes these policies very seriously and enforces them strictly.
Grading Policy: The final grade in this course will be determined as follows:
Quizzes and Projects 
25% 
Common Midterm Exam I 
20% 
Common Midterm Exam II 
20% 
Final Exam 
35% 
Your final letter grade will be based on the following tentative curve.

Attendance Policy: Attendance at all classes will be recorded and is mandatory. Please make sure you read and fully understand the Math Department’s Attendance Policy. This policy will be strictly enforced. Absences from class will inhibit your ability to fully participate in class discussions and problem solving sessions. Tardiness to class is very disruptive to the instructor and students and will not be tolerated. Students might be withdrawn from the class or receive an "F" because of absences.
MATLAB: MATLAB is a mathematical software program that is used throughout the science and engineering curricula. Several MATLAB assignments will be given out. These assignments have been designed to help you learn how to use this software in order to visualize many of the concepts taught in class.
Projects: It is vital that you complete the required assignments by the specified dates.
Quiz Policy: A short quiz based on the homework problems will be given weekly.
Exams: There will be two common midterm exams held during the semester and one comprehensive common final exam. Exams are held on the following days:
Common Midterm Exam I 
February 28, 2018 
Common Midterm Exam II 
April 11, 2018 
Final Exam Period 
May 4  10, 2018 
The time of the midterm exams is 4:155:40 pm for daytime students and 5:457:10 pm for evening students. The final exam will test your knowledge of all the course material taught in the entire course. Make sure you read and fully understand the Math Department's Examination Policy. This policy will be strictly enforced.
Makeup Exam Policy: To properly report your absence from a midterm or final exam, please review and follow the required steps under the DMS Examination Policy found here:
Cellular Phones: All cellular phones and other electronic devices must be switched off during all class times.

MATLAB Projects for M337:
Linear Algebra, Spring 2018
Visit the textbook website for supplementary materials including a guide to getting started with Matlab. For additional help, the math department has Matlab TA’s. Click for locations and times when they are available.
The first thing you need to do is to install the LayData toolbox on the computer where you will be using it. Here are the steps. I will assume that you have Matlab installed or are using Matlab on a campus PC.
 Download the LayData Toolbox.
 Uncompress the file and move the unzipped directory to the location on your computer where you want it.
 Add the toolbox to the Matlab search path. To do this run Matlab, and at the >> prompt, type pathtool to bring up the path management window. Click Add Folder, and select the folder containing the toolbox. Be sure to save it.

Lower Triangular Matrices 
March 5, 2018 
Problem (1c) and (2b) ask you to prove a result about lower triangular matrices. If you have trouble doing this in general, try it first with \(2\times2\) lower triangular matrices, then \(3\times3\) until you see the pattern. For general Matrices, try using the \(\Sigma\) notation for the \((i,j)\) entry of a matrix product.
