More specifically, I have 15 daily prices so what I did was building a vector from 0 to 15 and use flipr to reverse the order of my raw vector but it doesn't work because also the price of the option was reversed. Exp = []; %days to expiration. P = rand (1,15); %fake daily prices. plot (Exp,P) %is all reversed not just the days to expiration K 8 61 1. And more generally, you could use flipdim (a,dim). Where dim is the dimension (dim=1 flips rows, dim=2 flips columns). – David_G. Mar 6, at 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 You seem to be overthinking the problem. What you can do is use sort and independently apply the sorting to each column individually. The sort function uses a second parameter that tells you which dimension you want to apply the sorting. As you want to sort over the columns, you need to set the second parameter to 1, meaning that 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 indices

Is it possible in matlab/octave to use the sort function to sort an array based on the relative frequency of their elements? For example the array. m= [4,4,4,10,10,10,4,4,5] should result in this array: [5,10,10,10,4,4,4,4,4] 5 is the less frequent element and is on the top while 4 is the most frequent and it's on bottom 说明. 示例. B = flip (A) 返回的数组 B 具有与 A 相同的大小，但元素顺序已反转。. B 中重新排序的维度取决于 A 的形状：. 如果 A 为向量， flip (A) 将沿向量的长度方向反转元素顺序 生成されるコードを MATLAB と一致させるには、sortrows(real(A)) または sortrows(A,'ComparisonMethod','real') を使用します。 スレッドベースの環境 MATLAB® の backgroundPool を使用してバックグラウンドでコードを実行するか、Parallel Computing Toolbox™ の ThreadPool を使用してコードを高速化します。 Learn more about reverse a number MATLAB. Hi, I want to reverse a number, not a vector, like to I used fliplr, or flipud, or y = x(end: ), They just work for row vector. Please, help. Thank you Skip to content. Toggle Main Navigation. Sign In to Your MathWorks Account; 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 Select a Web Site. Choose a web site to get translated content where available and see local events and offers. Based on your location, we recommend that you select Arrays a and b are based on the sort of c (notice all the arrays are sorted based on the order Array c is sorted in) Final Array that I want: a= [2 6 4 5 3] b= [5 3 9 7 6] c= [1 3 6 8 9] Aloha Rick. PS: I'm using matlab/octave if there is a better way to do this please let me know
How to sort an array in descending order? - MATLAB Answers
Description. B = sort (A) sorts the elements of the real-valued fi object A in ascending order. If A is a vector, then sort (A) sorts the vector elements. If A is a matrix, then sort (A) treats the columns of A as vectors and sorts each column. If A is a multidimensional array, then sort (A) operates along the first array dimension whose size Matlab Atan2. The angle is positive for counter-clockwise angles (upper half-plane, y > 0), and negative for clockwise angles (lower half-plane, y sort() of Numpy or Matlab will progress counterclockwise. This can be verified using the Shoelace equation. Wikipedia Shoelace. Python Shoelace Sort index, returned as an index vector. The sort index describes the rearrangement of the rows in the input such that B = A(index:). The sortrows function uses a stable sorting I have a map [HOST](array1, array2) that I would like to sort according to the values in array1. There is a fairly large amount of data contained in the arrays (~50, elements in each). Is there a simple way to do this, perhaps using some built-in MATLAB feature? Environment is MATLAB array1 is a character array. Thanks in advance!
