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 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 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 反转字符串数组中的字符串，并找出反转之后读起来也一样的字符串。. str = [ "airport", "control tower", "radar", "runway"] str = 1x4 string. "airport" "control tower" "radar" "runway". newStr = reverse(str) newStr = 1x4 string. "tropria" "rewot lortnoc" "radar" "yawnur" 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 to 1 object (cf the first La funzione sort utilizza un algoritmo di ordinamento stabile. Quindi, quando l'input contiene valori ripetuti, l'indice di ordinamento conserva l'ordine originale dell'input, indipendentemente dalla direzione dell'ordinamento An alternative is to number ordermat, use intlut to replace each index value with it's number, then use sortrows, followed by the reverse intlut. hope that's clear - i don't know enough matlab to post a full answer, so adding as a comment. –
Reverse order of characters in strings - MATLAB reverse
Reverse y axis order. Learn more about reverse y axis, plot, axis properties. Hi. I have the following script (attached)b and the run that it opens can be found at this link. Find the treasures in MATLAB Central and discover how Reverse Strings. Reverse the strings in a string array and find strings that read the same when reversed. str = [ "airport", "control tower", "radar", "runway"] str = 1x4 Sorting. Sorting the data in an array is also a valuable tool, and MATLAB offers a number of approaches. For example, the sort function sorts the elements of each row or column of a matrix separately in ascending or descending order. Create a matrix A and sort each column of A in ascending order SORT_BACK (data = sort_back (data, indexes, dimension)) Sort back data to original order by using the indexes obtained from sorting and the B = sort (A) sorts the elements of 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 does not equal 1, treating the elements C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. Usage notes and limitations: str must be a string scalar, a character vector, or a cell array containing not more than one character vector @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
Ordenar los elementos de un arreglo - MATLAB sort - MathWorks
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] = For example, if I use the sort function on the array [14 8 91 19], I will get [8 14 19 91]. But instead I want [2 1 4 3] which gives me the indices of elements in the original array. Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! 6) Heap sort. 7) Insertion sort. 8) Merge sort. 9) Quicksort. 10) Radix sort. 11) Selection sort. 12) Shell sort. The code is written in such a way that it can be easily translated into other languages (e.g., each implementation should be quite efficient in C++) B = reordercats(A) reorders the categories in the categorical array, A, to be in alphanumeric [HOST] order of the categories is used by functions such as summary and [HOST] the categorical array is ordinal, the order of the categories defines their mathematical ordering.. The first category specified is the smallest and the last category is the larg Numlbl = length (lbl); % Determine number of lables. order = sort (numlbl,'descend'); % Create array of label numbers in descending order. newlbl = lbl (order); % Create new labels in descending order. legend (findobj ([HOST]en (2),'Type','area'),newlbl) % Set the legend to follow the new labels. hope this helps! I need to delete the double numbers in a vector and create a new vector without the doubles and maintaining the same order i used unique but i dont know how to let them stay in the same order! for exemple for 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 Sort函数排序. 在处理问题时，排序是一个非常常见的需求。. sort函数是Matlab内置的排序函数，可以满足常用的排序需求。. sort函数的基本形式如下. [Y,I] = sort(X,DIM,MODE) 1. Y表示对X排序后的结果. I 表示Y中对应元素原来在X中的下标. mode的默认值是‘ascend’升序排列
