MatLab的排序函数-sort，sort函数的调用格式: sort (X) 功能：返回对向量X中的元素按列升序排列的新向量。. [Y, I] = sort (A, dim, mode) 功能：对矩阵A的各列或各行重新排序，I记录Y中的元素在排序前A中位置，其中dim指明读A的列还是行进行排序。. 若dim=1，则按列排序； B = sortrows(A,column) sorts A based on the columns specified in the vector [HOST] example, sortrows(A,4) sorts the rows of A in ascending order based on the elements in the fourth [HOST]ws(A,[4 6]) first sorts the rows of A based on the elements in the fourth column, then based on the elements in the sixth column to break ties 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++) Group Data into Categorical Array. Group numeric data into a categorical array. Use the result to confirm the amount of data that falls within 1 standard deviation of the mean value. Group normally distributed data into bins according to the distance from the mean, measured in standard deviations. X = randn(,1); 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 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 Copy. [rows, columns] = size (X) sorted_X = reshape (sort (X (:), 'descend'), [columns, rows])'. It gives you the exact result you showed. It sorts all the elements, regardless of what row or column they started in, then reshapes from a vector back into the shape of the original X matrix. Mr. Suraj on 26 Dec Open in MATLAB Online.

Sort back data to original order - File Exchange - MATLAB Central
What does sorting by default in unique has to do with removing duplicate values? In same logic why doesnt sorting has default unique function built in? Or do I missing any point? For me it does not make any sense nor being logical. 1 Comment. Find the treasures in MATLAB Central and discover how the community can help you! Start KeySet = {'Jan', 'Feb', 'Mar', 'Apr'}; valueSet = [, , , ]; mapObj = [HOST] (keySet,valueSet); 5 Comments. Show 3 older comments. Adam on 5 May Edited: Adam on 8 May You can extract the keys and the values and do a sort on the keys, making sure to retain the 2nd output argument from sort - these @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 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 as vectors. example. B = sort (A,dim) returns the sorted
Matrix - How to sort specific rows in matlab - Stack Overflow
Matlab how do I sort my data? 3. plotting points from matrix on matlab. 0. R plot in ascending order. 3. Sorting barh plots in MATLAB. 0. plot scattered data in order (matlab) 1. Draw a curve correctly using Matlab? 0. how to plot a graph with the oryginal order of y-axis values? 1 This function takes the Matlab data from a struct and puts it into the table via a for-loop row for row. Because the data is put into the table via a for-loop I thought there might be a way to only sort a fixed number of rows at a time i.e row , , and so on In my case I need to reverse 16bit numbers, so, I've tried three methods: 1) Using fliplr () to reverse as per the suggestions: uint16(bin2dec(fliplr(dec2bin(data,16)))) To test out the speed I decided to try and checksum 12MB of data. Using the above code in my CRC, it took seconds to complete!

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 Select a Web Site.
