2、nd vector.It lists the structure from determinant,to matrix,tosolve system of linear equations,to vector,to structure of solutions,to eigenvalueand eigenvector,to quadratic form finally.Here is the structure of this book:Chapter 1 starts with determinant.There are three important points about thedet
3、erminant.The first is the definition,the second is property,and the last is itsexpansion.The Cramers rule is given basis on these three points.Chapter 2 gives all the varieties of matrix.After the study of concept ofmatrix,it begins with algebra operations,and shows some special matrices.It isfollow
4、ing with how to partition matrix,and how to find the inverse of matrix.After given the elementary operations and elementary matrix,this chapter is endedby rank of matrix.Chapter 3 shows the relationship between matrix and the system of linearequations.Certainly,it is the most important that using ma
5、trix to solve the systemof linear equations.Gaussian Elimination Method is the most helpful technique.Chapter 4 begins studying vector.Definition and operation are two basic studypoints.Linear dependence and rank of vector are two new knowledge structures.Chapter 5 is mainly basis on chapter 3 and c
6、hapter 4.Here is similarframework for giving the structure of solutions of homogeneous andnonhomogeneous system of linear equations.Both these two parts discuss thecorresponding property firstly,and give the details of their structure respectively.Chapter 6 is mostly in eigenvalue and eigenvector.Besides the definition ofthem,there are.three points of matrix using both two of them which arediagonalization,similar matrix and real symmetric matrix.Chapter 7 is quadratic form which has three points.The first point is about the
