% 根据第一列对矩阵进行排序 mat = [3, 2; 1, 4; 5, 0]; sortedMat = sortrows(mat); disp('Matrix sorted by first column:'); disp(sortedMat); % 根据第二列和第一列的组合对矩阵进行排序 sortedMatByCols = sortrows(mat, [2, 1]); disp('Matrix sorted by second and then first column...
I want to sort matrix A using the values in the column matrix B to have the C below: C=[A=[3 3 6; 5 5 9; 7 9 4; 2 2 5; 1 1 4; 8 1 2; 4 4 8; 6 8 5; 9 3 4] I have tried the code below, but it seems not to work ...
A(8)ans=14 使用单一下标引用数组中特定元素的方法称为线性索引。 如果尝试在赋值语句右侧引用数组外部元素,MATLAB 会引发错误。 test = A(4,5)Index exceeds matrix dimensions. 不过,您可以在赋值语句左侧指定当前维外部的元素。数组大小会增大以便容纳新元素。 A(4,5) =17A =4×51623130511108097612041415117 要...
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} ...
sort(m,1)% 给列进行排序 sort(m,2)% 给行进行排序 4、 单元数组 单元数组是索引单元格的数组,其中每个单元格可以存储不同维度和数据类型的数组。 cell函数用于创建单元格数组。单元格功能的语法是: C = cell(dim) C = cell(dim1,...,dimN) ...
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 ...
The function is used to enumerate the mean value of each column of the matrix, the specific effect is shown below: 5.sort函数(sort function)该函数用于对每列数值进行排序,具体效果如下图所示: The function is used to sort the values in each column, the specific effect is shown below: ...

First enter the original matrix in MATLAB: Sort by index type, with benefit index first and cost index second. Find the first column to start as a cost index. Cost_Column plays a very important role in defining the size of the column in the for loop. Automatic operation can be correctly...
