Hello everyone, I have a matrix of order n by m, I did the sorting using the function sort of matlab. My question is how to undo the sorting using the indices matrix. Thank you. [xs, indices] This is a strange answer because you do the sorting in-place but then the reversing out-of-place. If there is another variable aliasing the original list, its value afterwards will not have the elements in their original order, nor in descending order; the alias will point at a list sorted in ascending order. That could be rather surprising, and a You have a sortrows () function that you can use. Assuming you have two row vectors: Theme. Copy. sorted = (sortrows ([x',y'], 1))'. % reassigning sorted values. x = sorted (1:); y = sorted (2:); I just noticed that Jos has already mentioned, I left my answer here, it might be useful Select a Web Site.

Matlab中reverse函数. 在MATLAB中，reverse函数用于反转向量或矩阵中的元素顺序。. 它接受一个向量或矩阵作为输入，并返回一个与输入相同大小的向量或矩阵，但是元素顺序被反转了。. 例如，您可以使用以下代码创建一个向量v并反转其元素顺序：. 这将 I'm not sure, if I understand the question correctly. Do you want to bring B in the same order as the unsorted A? Then either sort both vectors and mix their sorting indicies: Theme. Copy. [As, Ai] = sort (A); [Bs, Bi] = sort (B (: 1)); ABi (Ai) = Bi; Now ABi is the sorting index to bring B to the order of A Choose the order from the name to obtain indexes and then use the indexes to sort the list. As an example: The names of the variables were chosen assuming that the number in the txts represent days. Use dir to obtain a list into a struct. Theme. Copy. list=dir ('*.txt') Convert the struct to cell array. Theme
MATLAB sort() vs Numpy argsort() - how to match results?
Viewed times. I have this problem that I need to sort a matrix in MATLAB. Input: (2x5 matrix) 1 2 3 4 5 6 7 8 9 And I'd like the output to be. (2x5) 9 설명. 예제. B = sort (A) 는 A 의 요소를 오름차순으로 정렬합니다. A 가 벡터인 경우 sort (A) 는 벡터 요소를 정렬합니다. A 가 행렬인 경우 sort (A) 는 A 의 열을 벡터로 취급하고 각 TblB = sortrows (tblA,'RowNames') sorts a table based on its row names. Row names of a table label the rows along the first dimension of the table. If tblA does not have row names, that is, if [HOST]es is empty, then sortrows returns tblA. This syntax is not supported when tblA is a timetable If you want to reverse a function you may use flip function: Theme. Copy. x = linspace (0,10); y = sin (x); x = flip (x); % reverse the values of x. plot (x,y) If you want to reverse the axes then here is an example code which you may use: Theme Turn the Position variable into a categorical array whose order matters (the array is an ordinal array.) The ordering is given by the desired_order list. ranks = categorical (Position, desired_order, 'ordinal', true) Store the data in a table array. results = table (ranks, Name, 'VariableNames', ["Rank", "Name"]) Sort index, returned as a vector, matrix, or multidimensional array. I is the same size as A. The index vectors are oriented along the same dimension that sort operates on. For 예를 들어, sortrows (A,'ComparisonMethod','abs') 는 크기를 기준으로 A 의 요소를 정렬합니다. [B,index] = sortrows (___) 는 B = A (index:) 를 충족하는, 행의 재배열을
