Linear algebra has been a very popular mathematics topic for self-learning recently, perhaps partly due to its application to machine-learning. Therefore, there are numerous resources about linear algebra on the Internet. The following are some of them that you may find useful:[br][br][br][url=https://www.youtube.com/playlist?list=PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab]"The Essence of Linear Algebra" - 3Blue1Brown[/url][br][br]Concepts in linear algebra are eloquently presented with lots of amazing animations. Some of the contents of this course are inspired by it. (The computational aspect of linear algebra is not touched upon though.)[br][br][br][url=https://www.khanacademy.org/math/linear-algebra]"Linear Algebra" - Khan Academy[/url][br][br]Khan Academy is always a good place to learn math. You can find many decent teaching videos about linear algebra there.[br][br][br][url=https://ocw.mit.edu/courses/mathematics/18-06sc-linear-algebra-fall-2011/]MIT online course on "Linear Algebra" by Gilbert Strang[/url][br][br]Online lecture videos of the MIT linear algebra course taught by the acclaimed mathematician Prof. Gilbert Strang. His textbooks "Linear Algebra and its Application" and "[url=https://math.mit.edu/~gs/linearalgebra/]Introduction to Linear Algebra[/url]" are certainly classics.[br][br][br][url=https://matrixcalc.org/en/]Matrix Calculator[br][/url][br]A very nice online calculator for matrices.[br][br][br][br][br][br][br]
