Welcome to Math 221. This blog provides you with some information about the course materials, exams, lecture notes and any news about the course. The text book for this course is: Linear algebra and its applications, by David Lay (Third Custom Edition for UBC). The skeleton lecture notes are partially completed and need to be filled during the course. They will be uploaded gradually as we progress and can be downloaded at the sidebar of this blog. I will upload the filled lecture notes at a later stage. You can also find some practical problems and additional materials here.
