MATH 22AL (Computer Laboratory For Linear Algebra) is a one-unit course for students enrolled in MATH 22A (Elementary Linear Algebra). The labs offered in this course are designed to help linear algebra students in two areas: First, the use of computers in computations related to linear algebra. Second, enhance students’ understanding of basic concepts and ideas of linear algebra covered in MATH 22A. These labs are not self-contained. They should be used as a supplement for an Elementary Linear Algebra course. For each lab, there is a set of prerequisite topics, which need to be studied and learned before doing the labs, which can be accomplish using any standard textbook. A little basic knowledge about working with computers is helpful. The labs are designed to use MATLAB. No familiarity with MATLAB is required. MATLAB command will be introduced gradually.
