本課程模塊包含交互式實(shí)況腳本，用于教授線性代數(shù)入門課程中常用的基本矩陣方法。在每個實(shí)況腳本的第一部分，學(xué)生學(xué)習(xí)標(biāo)準(zhǔn)定義、可視化概念并在紙上進(jìn)行練習(xí)。之后，學(xué)生練習(xí)互補(bǔ)的MATLAB方法。這些方法強(qiáng)化了討論的概念，幫助學(xué)生盡早熟悉計(jì)算軟件。每節(jié)課都以一個示例性應(yīng)用程序結(jié)束。這些實(shí)況腳本可以用作講座的一部分，作為教學(xué)環(huán)境中的活動，或作為課外完成的交互式作業(yè)。

This curriculum module contains interactivelive scriptsthat 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 DesktopDownload and unzip the repository. Then, double-click the MatrixMethods.prj file inside MATLAB.

Option 2:Open in MATLAB OnlineLog 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.
