SUMMARY

Matrix Analysis, Matrix Algebra, and Linear Algebra are distinct yet interconnected fields within mathematics. Linear Algebra primarily focuses on vector spaces and linear transformations represented by matrices. Matrix Analysis and Matrix Algebra can refer to the study of matrices as arrays of numbers or the examination of special types of matrices and their factorizations, often explored in physics and applied mathematics. A foundational understanding of Linear Algebra is essential before delving into Matrix Analysis or Matrix Algebra.

PREREQUISITES
  • Linear Algebra concepts, particularly vector spaces and linear transformations.
  • Understanding of matrices as mathematical structures.
  • Basic knowledge of matrix factorizations and their applications.

Matrix Alalysis, Matrix Algebra, Linear Algebra, they seem to cover many similar topics.

Would someone explain about what are the differences between them?

Thanks in advance.

Linear algebra is focused on vector spaces. Linear transformations between vector spaces can be represented by matrices so linear algebra emphasizes matrices in that context.

It's possible to study matrices simply as arrays of numbers without emphasizing that they represent linear transformations and I have seen books like that. They were mainly designed for non-mathematicians who needed to a little about matrices for some application, such as statistics or linear programming. However, I don't know whether to call such an approach "matrix analysis" or "matrix algebra". Did you have specific books with those titles in mind?

Special types of matrices and special ways to factor matrices into simpler types of matrices are studied in physics and applied mathematics. This could also be called "matrix analysis" or "matrix algebra". These would be topics a person normally studies only after taking an introductory course in Linear Algebra.
