Course title
Linear Algebra
Course description
We conduct in-person (face-to-face) classes in Spring 2023. Those who are based abroad and wish to take the classes online should contact the lecturer via email (ikegami@shibaura-it.ac.jp).

In this course, you will learn the basic theory of matrices and their algebras with applications to linear equations and differential equations. Starting with how to represent linear equations via matrices, you will study the row and column operations of matrices with its application to solving linear equations with Gaussian elimination. Looking at solution sets of linear systems, you will reach the notions of linear independence of vectors, linear transformations, and vector spaces. Then you will learn the rank, determinant, eigenvalues, and eigenvectors of matrices to characterize the basic properties of matrices and linear equations. You will also see the correspondence between matrices and linear transformations of vector spaces.
Purpose of class
You are expected to obtain skills, knowledge, and understandings of basics of matrices and linear transformations, which are widely used in science and engineering.
