Description. example. newStr = reverse (str) reverses the order of the characters in str. Examples. collapse all. Reverse Strings. Reverse the strings in a string array Sort the elements of a complex vector by their real parts. By default, the sort function sorts complex values by their magnitude, and breaks ties using phase angles. Specify the value of 'ComparisonMethod' as 'real' to instead sort complex values by their real parts How to reverse "sort" - MATLAB Answers - MATLAB Central.

For example we have a row like. m= [1 6 2 8 9] [Y,I] = sort (m) then it gives you. Y = Theme. Copy. 1 2 6 8 9. I = Theme. Copy. 1 3 If A is a cell array of character vectors or a string array, then sort(A) sorts the elements according to the code order for the UTF character encoding scheme. Sort back data to original order by using the indexes obtained from sorting and the sorted dimension. Supports arrays of any dimension, and
How to sort all elements of a 2d matrix in MATLAB?
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 2 Answers. Sorted by: 3. That's just some basic matrix indexing, using the colon operator: M (end: ) Share. Improve this answer. Follow. answered Nov 28, at Daniel. k 3 36 Add a comment. 2. Flip the array upside down by using flipud. A = [1, 2; 3, 4; 5, 6; 7, 8; 9, 10]; B = flipud (A); Share. Improve this answer. Follow 4 Answers. Sorted by: Step 1: Find the unweighted mean of the vertices: cx = mean (x); cy = mean (y); Step 2: Find the angles: a = atan2 (y - cy, x - cx); Step 3: Find the correct sorted order: [~, order] = sort (a); Step 4: Reorder the coordinates: x = x (order); y = y (order); Share. Follow. edited Sep 4, at Description. example. B = flipud (A) returns A with its rows flipped in the up-down direction (that is, about a horizontal axis). If A is a column vector, then flipud (A) returns a vector of the same length with the order of its elements reversed. If A is a row vector, then flipud (A) simply returns A Syntax. B = flip (A) B = flip (A,dim) 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 4 Answers.

MATLAB has a nice function sortrows to sort matrices (numeric or cells) based on specific column (s). I use it often when I am doing some data 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 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 y2 = sort_back (y, ind, 2); Also works on cellstrings (vectors) Fighting in the Falls by Loser_With_Fedora.

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
