一起来学演化计算-matlab基本函数sort觉得有用的话,欢迎一起讨论相互学习~Follow Mesort对数组元素排序语法B = sort(A) 按照大小不等于1的第一个数组维度对A的元素按升序排序如果A是一个向量，那么sort(A)对向量元素进行排序如果A是一个矩阵，那么sort(A)将A的列作为向量，并对每一列进行排序如果A是一个 The sortrows answer by @chaohuang is probably what you're looking for. However, it sorts based on all columns. If you only want to sort based on the first column, then you can do this: % sort only the first column, return indices of the sort. [~,sorted_inds] = sort(a(:1)); % reorder the rows based on the sorted So I can take the row number, grab the Node number regarding to the sort index from the original data and place it in the first column of my sorted data. So my first Idea would be to solve the problem with a loop. Theme. Copy. for i = 1:length (Sortierung) Sortierung (i,1)=Auswertung (index (i),1) end 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, TblB = sortrows (tblA) 는 테이블 또는 타임테이블의 행을 정렬합니다. tblA 가 테이블인 경우 sortrows 는 첫 번째 변수의 값을 기준으로 tblA 를 오름차순으로 정렬합니다. 첫 번째 변수에서 요소가 반복되는 경우 sortrows

For example we have a row like. m= [1 6 2 8 9] [Y,I] = sort (m) then it gives you. Y. Theme Accepted Answer: Adam. test_exp.m. Hi. I have the following script (attached)b and the run that it opens can be found at this link. 如果 A 为矩阵， flip (A) 将反转每列元素的顺序。. 如果 A 为 N 维数组， flip (A) 将按 A 的大小值不等于 1 的首个维度上进行运算。. 示例. B = flip (A,dim) 沿维度 dim 反转 A 中元素的顺序。. 例如，如果 A 为矩阵， flip (A,1) 将反转每一列中的元素， flip (A,2) 将反转每一 Si A es un escalar, sort(A) devuelve A. Si A es complejo, de forma predeterminada sort ordena los elementos por magnitud. Si más de un elemento tiene la misma magnitud, los Answers (2) Walter Roberson on 13 May polynomials of degree 2 or higher cannot be inverted to give a polynomial. The inverse of the particular polynomial you indicate is the union of three expressions. If you have the symbolic toolbox, you can use solve () Marcin Konowalczyk on 1 Nov @Walter is Description. 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. If A is a matrix, then flip (A) reverses the elements in each column B = sort (___,direction) は、前述の構文のいずれかを使って direction で指定された順序で並べ替えた A の要素を返します。. 'ascend' は昇順 (既定) を示し、 'descend' は降順を

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 Direction は昇順の場合は 'ascend' (既定値)、降順の場合は 'descend' です。. また、 direction は要素が 'ascend' と 'descend' である cell 配列にすることもでき、この場合、 E = [[HOST]]; F = sort (E, 'descend');% Sort in descending order. %%Create histogram. G = histogram (C, []); xlabel ('Label of connected objects') ylabel ('Pixel length') title ('Length of connected objects') I was able to produce this histogram: Now I would like to: 1/ make each bar of the histogram corresponding 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" 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 7. Oddly enough macOS Finder does not (seem to) offer a reverse sort in anything but list view. You can change the sort order in list view by clicking on the column heading and noting the direction the arrow points, either up or down. But a sort order does not seem to be available in anything but list view 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 @Asen Martin is this a solution? You said you want to "sort a matrix," which is in general different from flipud, although they are the same for your [HOST]'s not clear whether you want to sort each column individually, or as groups using sortrows. – Jeff Irwin
