Review of Linear Algebra¶
This note is an introduction to Linear Algebra for future study.
1. Overview¶
As you can see, I was studying GAMES 101 just for fun. It was relaxing at the beginning until I met the Lecture 03 -- Transformation... So, I went back to review and organize what I have learned for moving on.
You can see I was noting with English even though I am completely Chinese, hh... Simply because the lecture is in English for the whole time, and I was immersing in this Environment and found it interesting.
The second reason is that I want to attempt a new way to manage my note and practice my English writing in the same time. I will use DeepSeek or other AI to correct it, so you will see some non-typical expression in my post.
In this post, you will see: - Vectors - Vector Normalization - Vector Addition - Cartesian Coordinates - Vector Multiplication - Orthonormal bases and coordinate frames - Dot Product - Cross product - Matrices - What is a matrix - Matrix-Matrix Multiplication - Matrix-Vector Multiplication - Transpose of a Matrix - Identity Matrix and Inverses - Vector multiplication in Matrix form
2. Vectors¶
I think noting in this way is too slow, I will not do this again...
Translation Glossary¶
- Orthonormal 正交
- coordinate frames 坐标系
- cross product 叉积
- Identity Matrix 单位矩阵
