Elementary Linear Algebra by Muhammad Usman Hamid

Linear Algebra is the study of vectors and linear transformations. The main objective of this course is to help students learn in rigorous manner, the tools and methods essential for studying the solution spaces of problems in mathematics, engineering, the natural sciences and social sciences and develop mathematical skills needed to apply these to the problems arising within their field of study; and to various real world problems.

Our sincere gratitude goes out to Muhammad Usman Hamid for providing these notes and for making the effort to post them on MathCity.org.
