Theme. Copy. [B,I] = sort (A); [~,J] = sort (I); B (J) If you have a matrix/array, then you first need to define what the intended effect is: to sort elements along one dimension (e.g. separately sort each column or row of a matrix) or to sort the rows atomically (i.e. using SORTROWS). 4 Comments 1 Answer. Sorted by: 7. x() = sortrows(x(), 1:size(x,2)); The second argument of sortrows tells it which columns in which order you want to sort. so 1:size (x, 2) will sort by each column in turn (in ascending order) If you actually want all the columns to be perfectly sorted (rows 1 to 10) and not keep the row integrity (i.e How to reverse "sort". Learn more about sort For example we have a row like m=[1 6 2 8 9] [Y,I] = sort(m) then it gives you Y = 1 2 6 8 9 I = 1 3 2 4 5 But I would like to sort This package contains MATLAB implementations of the following common sorting algorithms. 1) Bubble sort. 2) Bucket sort. 3) Cocktail sort. 4) Comb sort. 5) Counting sort. 6) Heap sort Reverse the strings in a string array and find strings that read the same when reversed. str = [ "airport", "control tower", "radar", "runway"] str = 1x4 string. "airport" "control tower" My attempt: a = [HOST]([[2,1,1],[3,3,1],[3,2,2]]) b = [0,2,1] idx = [i[0] for i in sorted(enumerate(b), key=lambda x:x[1])] The problem is that I cannot find a way to build the anew matrix as I did using Matlab. I have tried: anew=a[idx] anew. array([[2, 1, 1]

Reverse the strings in a string array and find strings that read the same when reversed. str = [ "airport", "control tower", "radar", "runway"] str = 1x4 string. "airport" "control tower" "radar" "runway". newStr = reverse(str) newStr = 関数 sort は安定した並べ替えアルゴリズムを使用します。そのため、入力に繰り返しの値が含まれている場合、並べ替えインデックスは、並べ替えの方向に関係なく、入力に Exemple. B = flip (A,dim) inverse l’ordre des éléments dans A le long de la dimension dim. Par exemple, si A est une matrice, alors flip (A,1) inverse les éléments dans chaque colonne, et flip (A,2) inverse les éléments dans chaque ligne Sort back data to original order by using the indexes obtained from sorting and the sorted dimension. Supports arrays of any dimension, and cellstrings. Works on 3 Answers. And more generally, you could use flipdim (a,dim). Where dim is the dimension (dim=1 flips rows, dim=2 flips columns). If the array you want to reverse is a range a:b, then it is much faster to use Sort 函数使用一种稳定的排序算法。因此，当输入包含重复值时，无论排序方向如何，排序索引都会保留输入的原始顺序。例如，如果 A = [1 2 1 2]，则 [Ba,Ia] = sort(A,'ascend') 返回排序索引 Ia = [1 3 2 4]，[Bd,Id] = sort(A,'descend') 返回排序索引 Id = [2 4 1 3]。 Description. example. B = flip (A) returns array B the same size as A, but with the order of the elements reversed. The dimension that is reordered in B depends on the shape of A: If A is vector, then flip (A) reverses the order of the elements along the length of the vector Description. example. B = flip (A) returns array B the same size as A, but with the order of the elements reversed. The dimension that is reordered in B depends on the shape of A:

関数 sort は安定した並べ替えアルゴリズムを使用します。そのため、入力に繰り返しの値が含まれている場合、並べ替えインデックスは、並べ替えの方向に関係なく、入力における元の順序のままになります。 Exemple. B = flip (A,dim) inverse l’ordre des éléments dans A le long de la dimension dim. Par exemple, si A est une matrice, alors flip (A,1) inverse les éléments dans chaque Sort back data to original order by using the indexes obtained from sorting and the sorted dimension. Supports arrays of any dimension, and cellstrings. Works on arrays of any dimension: y = randn (3,4,2); [y,ind] = sort (y,2); do stuff with sorted y
