Information

This curriculum module contains interactive MATLAB® live scripts that apply fundamental concepts and basic terminology related to linear algebra. There is a focus on identifying applications of linear algebra to academic disciplines beyond mathematics.

Background

You can use this live script as demonstrations in lectures, class activities, or interactive assignments outside class. Applied Linear Algebra covers topics from a first course in linear algebra including vector and matrix arithmetic, solving matrix equations, null spaces, eigenvalues, and eigenvectors. Applications include balancing chemical reactions, solving static force scenarios, encryption, systems modeling, and explainable machine learning.

The instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the EndIcon.png Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.

Solutions are available upon instructor request. Contact the MathWorks online teaching team if you would like to request solutions or have a question.

Prerequisites

These scripts assume knowledge of basic linear algebra such as vectors, matrices, eigenvalues, and eigenvectors, as discussed in the related courseware on matrix methods. The focus of these scripts is on reinforcing the theoretical knowledge of linear algebra concepts by applying them in a variety of domains. There is minimal MATLAB knowledge required for these scripts, but you could use MATLAB Onramp as a resource to acquire familiarity with live scripts and MATLAB syntax.

Getting Started

Accessing the Module

On MATLAB Online:

Use the OpenInMO.png link to download the module. You will be prompted to log in or create a MathWorks account. The project will be loaded, and you will see an app with several navigation options to get you started.

On Desktop:

Download or clone this repository. Open MATLAB, navigate to the folder containing these scripts and double-click on [AppliedLinAlg.prj](matlab: openProject("AppliedLinAlg.prj")). It will add the appropriate files to your MATLAB path and open an app that asks you where you would like to start.

Ensure you have all the required products (listed below) installed. If you need to include a product, add it using the Add-On Explorer. To install an add-on, go to the Home tab and select AddOnsIcon.png Add-Ons > Get Add-Ons.

Working through the module:

  1. In the opening app, select "Main Menu" to open a brief hyperlinked navigation page or "README" to open this page. To give us feedback, select "Feedback".
  2. Get started with each topic by clicking the link to open the live script. The instructions inside each live script will walk you through the live script and related functions.

Products

MATLAB® is used throughout. Tools from the Symbolic Math Toolbox™ are used frequently as well. The sevilla.jpg image in Steganography.mlx comes from the Image Processing Toolbox™. The IdentifyDigits and ReadMyWriting scripts use both the Image Processing Toolbox™, and the Statistics and Machine Learning Toolbox™. IdentifyDigits also uses the Deep Learning Toolbox™ while ReadMyWriting uses MATLAB Mobile.
