這門課的課程筆記, 當作複習一下也是不錯的: https://www.coursera.org/learn/matrix-algebra-engineers/home/module/1

Text book: https://www.math.hkust.edu.hk/~machas/matrix-algebra-for-engineers.pdf

Week 1 Matrices

Week 2 Systems of Linear Equations

Week 3 Vector Spaces

Week 4 Eigenvalues and Eigenvectors

以前學的線性代數這裡很多沒說到, 譬如什麼是相似矩陣, Jordon form, SVD, singular value 等等

不過作為初步的複習也是門不錯的課程

非常推薦周老師的網頁: https://ccjou.wordpress.com/
