Curriculum Module

Created with R2020b. Compatible with R2020b and later releases.

# Information

This curriculum module contains interactive MATLAB® live scripts that teach the fundamental concepts of vectors, such as vector magnitude and addition.

## Background

You can use these live scripts as demonstrations in lectures, class activities, or interactive assignments outside class. VectorBasics is an interactive lesson that teaches the basics of individual vectors, such as vector components, vector magnitude, and vector orientation. VectorArithmetic is an interactive lesson that teaches vector arithmetic. Vector addition, scalar multiplication, dot product, and cross product are discussed. These methods are motivated by an application: calculating the orientation of a cell phone using the built-in accelerometer and magnetometer. Throughout the module, students apply the mathematical techniques to computing meaningful values, such as pitch and yaw.

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 Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.

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

## Prerequisites

This module assumes knowledge of high school algebra and trigonometry. It does not assume any MATLAB knowledge. All scripts are intended to be used in Hidden Code mode.

## Getting Started

### On Desktop:

Download or clone this repository. Open MATLAB, navigate to the folder containing these scripts and double-click on VectorArithmetic.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 Add-Ons > Get Add-Ons.

## Products

MATLAB® and Symbolic Math Toolbox™ are used throughout this module.

# Scripts

## VectorBasics.mlx

In this script, students will...
• Relate the components of a vector to its visualization in 2- and 3-dimensions
• Compute the magnitude of a vector in 2- and 3-dimensions
• Compute the orientation of a vector in 2-dimensions
• Discuss the meaning of the magnitude of an accelerometer reading
• Relate the pitch of a cell phone to accelerometer readings

## VectorArithmetic.mlx

In this script, students will...
• Compute scalar, dot, and cross products of vectors
• Relate arithmetic vector operations to visual representations
• Identify the physical meaning of the results of arithmetic vector operations
• Apply vector arithmetic to compute the yaw of a cell phone
