The Theoretical and Applicable Analysis of Equivalence, Congruence and Similarity Between Matrices and Matrix Decomposition
Abstract: Three kinds of common used relationships between any two matrices, equivalence, congruence and similarity, and matrix decomposition are summarized in this paper from both theoretical and applicable aspects. Based on the basic concept of the relationships between matrices, this paper introduces the related theory of matrices, and mainly presents a necessary and sufficient condition, sufficient conditions and necessary condition for the establishment of the specific relationship. The paper also summarizes the differences and relationships among these three concepts. On the basis of these discussions, it is proved that the establishment of the matrix decomposition, also called the matrix factorization, which reflects the method of matrix decomposition. The practical applications of the matrix decomposition are also given to enrich the theory.
Key words: Equivalence; Congruence; Similarity; Matrix Decomposition; Application
