《矩阵与变换》是新增加的内容,共有六章,本文针对其前三章“二阶矩阵与平面向量”、“几种常见的平面变换”和“变换的复合与矩阵的乘法”。一、学习建议1.学习第一章“二阶矩阵与平面向量”时,要注意几个问题,即:(1)初次接触矩阵概念时,可以先尝试将一些具体问题用数表形式来表示,熟练以后再尝试用矩阵来表示。 “Matrix and Transformation” is a newly added content. There are six chapters. This article focuses on the composition and matrix of the first three chapters: “second-order matrix and plane vector,” and several common plane transformations“ and ”“ transformations. Multiplication of ”. First, learning suggestions 1. When learning the first chapter “second-order matrix and planar vector ”, pay attention to several issues, namely: (1) when the concept of initial contact with the matrix, you can try to use some of the specific problems in the form of a number table To show that skill will later try to use the matrix to represent.
