The meaning of RANK OF A MATRIX is the order of the nonzero determinant of highest order that may be formed from the elements of a matrix by selecting arbitrarily an equal number of rows and columns from it.
We define the rank of a matrix as the number of linearly independent rows which it contains.我们把这个矩阵的秩定义为它所包含的线性无关行的数目。
Matrix的Rank在中文里就是”矩阵的秩“将矩阵做初等行变换后，非零行的个数叫行秩 将其进行初等列变换后，非零列的个数叫列秩 矩阵的秩是方阵经过初等行变换或者列变换后的行秩或列秩 比如给你两个或者三个含有x y z的等式，怎么用这个方法找出几个等式有几个解 就是叫你抽象为Matrix进行解答...

Green, in Mathematical Tools for Applied Multivariate Analysis, 1997 4.6.3 The Rank of a Matrix The concept of matrix rank is related to two topics that have already been discussed in earlier chapters: 1. linear dependence of a set of row or column vectors, 2. the determinant of a matrix...
A. The matrix is very small. B. The system has a unique solution. C. The matrix is very big. D. The system has no solution. 相关知识点: 试题来源: 解析 B。解析:文中明确指出如果矩阵的秩是满的,那么方程组有唯一解。A 选项矩阵大小与秩满不满无关;C 选项同理;D 选项与满秩时的情况...
The column rank of a matrix is the dimension of the linear space spanned by its columns. The row rank of a matrix is the dimension of the space spanned by its rows. Since we can prove that the row rank and the column rank are always equal, we simply speak of the rank of a ...
The echelon form of a matrix is a vital idea that was first introduced when mathematicians were looking to find general methods for solving systems of linear equations. This definition is used to subsequently define the “reduced echelon form” of a matrix, which we will not describe in this ...
