本课程模块包含交互式实况脚本,用于教授线性代数入门课程中常用的基本矩阵方法。在每个实况脚本的第一部分,学生学习标准定义、可视化概念并在纸上进行练习。之后,学生练习互补的MATLAB方法。这些方法强化了讨论的概念,帮助学生尽早熟悉计算软件。每节课都以一个示例性应用程序结束。这些实况脚本可以用作讲座的一部分,作为教学环境中的活动,或作为课外完成的交互式作业。
This curriculum module contains interactive live scripts that teach fundamental matrix methods commonly taught in introductory linear algebra courses. In the first part of each live script, students learn standard definitions, visualize concepts, and perform exercises on paper. Afterward, students practice complementary MATLAB methods. These methods reinforce the discussed concepts and help students to develop an early familiarity with computational software. Each lesson concludes with an illustrative application. These live scripts can be used as part of a lecture, as activities in an instructional setting, or as an interactive assignment to be completed outside of class.
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.
Get started with the interactive examples
Option 1: Download to Desktop Download and unzip the repository. Then, double-click the MatrixMethods.prj file inside MATLAB.
Option 2: Open in MATLAB Online Log in to your MathWorks account to access your license. If you are associated with a university, use your university email to access a license.
From there, you can follow the landing page instructions to get started with the examples.
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, if a loop is running longer than intended), click the Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.
