Qian Xiyuan is a Chinese author about whom relatively limited public information is available. The only confirmed work is Linear Algebra (Third Edition), a book commonly classified under exam preparation and intended for readers whose main goals are exam readiness and course review. The subject belongs to linear algebra, a foundational university mathematics course, and works of this kind typically cover core topics such as matrices, vectors, and systems of linear equations, with attention to precise definitions and the training of problem-solving methods. As the compiler of a textbook or study guide, Qian Xiyuan's role is mainly one of organizing, arranging, and presenting existing teaching content rather than conducting original theoretical research. Since only one work is held in the collection, a full assessment of the author's writing style and academic orientation is difficult; readers should choose the book in light of their own course requirements and exam syllabi, using it as one reference for review and practice.
