Immersive Linear Algebra is a free interactive textbook written by Jacob Strom, Kalle Astrom and Tomas Akenine-Moller. The figures are interactive, so vectors, planes, matrices and transformations can be moved and rotated directly in the page to see how a result changes.
The book covers vectors, dot and cross products, matrices, systems of linear equations and determinants, with a visual explanation placed next to each definition. The geometric approach is aimed at readers who need the subject for computer graphics, mechanics, signal processing or machine learning.
A lot of sketches, and interactive tools.
It works in the browser without installation or registration. The book is a teaching text, so it explains concepts and worked examples but does not offer a calculator for arbitrary matrices.
