Linear algebra is the basic theory of high numbers. As long as you need to learn advanced mathematics, you need to learn linear algebra. Linear algebra is a branch of mathematics, and its research objects are vectors, vector spaces, linear transformations and finite-dimensional linear equations. Vector space is an important subject in modern mathematics. Therefore, linear algebra is widely used in abstract algebra and functional analysis. Through analytic geometry, linear algebra can be expressed concretely.

Postgraduate is a kind of education in higher education, which is divided into master's degree and doctor's degree. Graduate students are mainly divided into full-time and part-time students. Full-time and part-time graduate students implement the same examination enrollment policies and training standards, and their academic degree certificates have the same legal status and the same effect.
