채택된 답변:Guillaume Let's say, I have the matrix: A=[x,y]=[1.1 2;1.2 4;1 4;1.1 3 ;1.3 2;1.3 4;1 2;1.2 3;1.3 3;1.2 2;1 3;1.1 4]; As you observed that:the value of 1st column vary from 1 to 1.3
1 function r = rank(A,tol) 2 % RANK Matrix rank. 3 % RANK(A) provides an estimate of the number of linearly 4 % independent rows or columns of a matrix A. 5 % RANK(A,tol) is the number of singular values of A 6 % that are larger than tol. 7 % RANK(A) uses the default...
上面的意思是说,在sort函数中,有两个参数,一个参数是dim,dim表示的是按照哪一维排序,如行为1,列为2;第二个参数是mode,mode表示的是按照降序或者升序排列(缺省的时候是升序排列)。 对于矩阵 A=\begin{pmatrix} 5 & 7 & 8 \\ 4 & 6 & 1 \\ 8 & 0 & 7 \end{pmatrix} ...
SORTROWS(X,COL) sorts the matrix based on the columns specified in the vector COL. If an element of COL is positive, the corresponding column in X will be sorted in ascending order; if an element of COL is negative, the corresponding column in X will be sorted in descending order. For...
This video covers how to sort a matrix, either sorting each column independently or sorting such that the original rows stay together. Most new users are able to find the SORT command without much problem, but the very useful SORTROWS is often missed. ...
从上述的结果看出,sort函数会比较矩阵中的每一个元素,将行中的每一个元素或者列中的每一个元素按照升序排列。 若现在需要将矩阵按照行排序,可以任意指定排序比较的列。可以使用sortrows函数。 2、sortrows函数 SORTROWS(X,COL) sorts the matrix based on the columns specified in the ...
