DIM的默认值是1,如果X是矩阵,则默认对矩阵的各个列进行升序排列,即sort(X,1)与sort(X)等效(矩阵在matlab中是按列存储的) sort(X,2)表示对矩阵的各行中的元素按照升序排列 如果X是行向量,则Y与I也是行向量;如果X是列向量,则Y与I也是列向量,如果X是矩阵,则Y与I是与X维数相同的矩阵 -由于在排序的时候...
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 example, SORTROWS(X,[2 -3]) sorts the rows of X first in ascending order for the second column, and then by descending order for the third...

B = sort(A,dim,direction) 1. sortrows的功能是,将矩阵或者cell根据某一列进行升序或降序排列,其中A代表待处理的矩阵或cell数据,column代表根据第几列进行排序,direction的选择有'ascend'或 'descend',分别代表升序和降序 B = sortrows(A,column ,direction) ...
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 按行升序: 按列升序: 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...
