This chapter presents a selective survey of both areas. It reviews the concepts of linear dependence and orthogonality of vectors and the rank of a matrix. A major reason related to the usefulness of matrix methods is that many topics in econometrics have a multivariate character. The chapter ...

选择一种排秩方法。 Inlinear algebra, therankof amatrixAis thedimensionof the vector space generated (or spanned) by its columns.[1]This is the same as the dimension of the space spanned by its rows.[2]It is a measure of the "nondegenerateness" of thesystem of linear equationsandlinea...
The Rank of a Matrix: The dimension of column space is the rank of a matrix. To find the rank transform the matrix to its row echelon form. Then the number of non-zero rows gives the rank of the matrix. Matrix Properties: A matrix is a set...

Chapter 2 Algebra of Matrices For a single element a_{ij}, i shows which row the element is in, j shows which column the element is in. E.g. 'm \times n' means this matrix has m rows and n columns. 'A zero matrix always equals to another zero matrix'is true or false?
The rank of matrix A, denoted rank(A), is the common dimension of the row space and column space of matrix A ? The nullity of matrix A, denoted nullity(A), is the dimension of the nullspace of A 0 z ~ m COMPLEX MATRICES ? Entries are all complex numbers, a + bi ? The ...
