Public information about Lu Gang is limited: all that is known is a single work, Linear Algebra, classified on this site under exam preparation. This suggests that the author's writing focuses on foundational mathematics courses and study or test-preparation support, aimed at students who need to review linear algebra systematically and prepare for related examinations. Linear algebra is a core course for science, engineering, and economics and management students; its content is abstract and dense with symbols and derivations, making it demanding for beginners. Books of this kind typically need to balance conceptual explanation, worked examples, and exercise practice, helping readers connect definitions, theorems, and computational steps into usable problem-solving routines. Because no biographical, educational, or professional details are available, the author's teaching background cannot be confirmed, nor should the specific features of the writing style be inferred. The work can only be judged as serving the practical needs of course study and exam preparation, suitable as supplementary review material.
