This paper investigates the algebraic relationships between the dimension-keeping semi-tensor product of matrices (DK-STP) and the semi-tensor product of matrices (STP). Firstly, the definitions of five types of STPs and the type-I DK-STP are given. Secondly, the fundamental properties of the type-I DK-STP are introduced. Thirdly, the algebraic relationships between the type-I DK-STP and these five types of STPs are explored respectively. Finally, the DK-STP is generalized, and the algebraic relationships between the right DK-STP and the right STPs are discussed.

摘要

This paper investigates the algebraic relationships between the dimension-keeping semi-tensor product of matrices (DK-STP) and the semi-tensor product of matrices (STP). Firstly, the definitions of five types of STPs and the type-I DK-STP are given. Secondly, the fundamental properties of the type-I DK-STP are introduced. Thirdly, the algebraic relationships between the type-I DK-STP and these five types of STPs are explored respectively. Finally, the DK-STP is generalized, and the algebraic relationships between the right DK-STP and the right STPs are discussed.
