矩阵Kronecker乘积的性质与应用
摘要
按照矩阵乘法的定义，我们知道要计算矩阵的乘积AB，就要求矩阵A的列数和矩阵B的行数相等，否则乘积AB是没有意义的。那是不是两个矩阵不满足这个条件就不能计算它们的乘积呢？本文将介绍矩阵的一种特殊乘积B
A ，它对矩阵的行数和列数的并没有具体的要求，它叫做矩阵的Kronecker积（也叫直积或张量积）。
本文将从矩阵的Kronecker积的定义出发，对矩阵的Kronecker 积进行介绍和必要的说明。之后，对Kronecker积的运算规律，可逆性，秩，特征值，特征向量等性质进行了具体的探究，得出结论并加以证明。此外，还对矩阵的拉直以及矩阵的拉直的性质进行了说明和必要的证明。
矩阵的Kronecker积是一种非常重要的矩阵乘积，它应用很广，理论方面在诸如矩阵方程的求解，矩阵微分方程的求解等矩阵理论的研究中有着广泛的应用，实际应用方面在诸如图像处理，信息处理等方面也起到重要的作用。本文讨论矩阵的Kronecker积的性质之后还会具体介绍它在矩阵方程中的一些应用。

Abstract
According to the definition of matrix multiplication, we know that to calculate the matrix product AB, requires the number of columns of the matrix A and matrix B is equal to the number of rows, otherwise the product AB makes no sense.That is not two matrices not satisfy this condition will not be able to calculate their product do?This article will describe a special matrix product B
A , the number of rows and columns of a matrix and its no specific requirements, it is called the matrix Kronecker product (also called direct product or tensor product).
This paper will define the matrix Kronecker product of view, the Kronecker product matrix are introduced and the necessary instructions. Thereafter, the operation rules Kronecker product, the nature of reversibility, rank, eigenvalues, eigenvectors, etc. specific inquiry, draw conclusions and to prove it. In addition, the properties of the stretch of matrix and its nature have been described and the necessary proof.
Kronecker product matrix is a very important matrix product, its use is very broad, theoretical research, and other matrix solving differential equations, such as solving the matrix equation matrix theory has been widely applied in practical applications such as image processing aspects of information processing, also play an important role. After the article discusses the nature of the matrix Kronecker product it will introduce a number of specific applications in the matrix equation. Keywords:
Matrix; Kronecker product; Stretch of matrix; Matrix equation; Matrix Differential Equations
