MAT2041 Linear Algebra: Theory and Applications

This is a new and fundamental course designed for the freshmen in the school of data science (SDS). Different from traditional linear algebra courses, we introduce a modern syllabus and try to make the fundamental concepts in linear algebra more understandable while also provide students with rigorous math training. Instead of starting the first lecture by introducing methods to solve a system of linear equations, we think it is not only important to tell the students *how*, but also *why* to solve the problems. Lots of data science problems are provided to motivate the need of mathematical treatment and concepts, and demonstrate the usefulness of linear algebra.
