Teachers TSURUTA YOSHIHIRO Year 1　1st semest [Department of Aerospace Engineering, Faculty of Science and Engineering] Basic Major Subjects Requisites　2credit 2G102

Course Description

This course covers matrix theory and linear algebra, which are a branch of mathematics and are useful in natural science and engineering. The items are as follows: Matrix, linear transformation, inverse matrix, determinant, inverse matrix and simultaneous linear equations, diagonalization and Eigen values of matrix, and linear independency of vectors. The classes consist of lectures and exercises. This subject is related to the clause 1 of the diploma policy of the Department of Aerospace Engineering.

Course Objectives

After successfully completing the course, you will have a good understanding of the following topics and their applications:
- Matrix operations, including inverses
- Linear dependence and independence
- Determinants and their properties
- Cramer's rule, Sweep method
- Eigenvalues and eigenvectors
