Ebook: Linear Algebra Problem Book

"The book is addressed to students (and teachers) of undergraduate linear algebra—it might supplement but not (I hope) replace my old 'Finite Dimensional Vector Spaces'. It largely follows that old book in organization and level and order—but only 'largely'—the principle is often violated. This is not a step-by-step textbook—the problems vary back and forth between subjects, they vary back and forth from easy to hard and back again. The location of a problem is not always a hint to what methods might be appropriate to solve it or how hard it is."
