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! 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 The vector A is sorted as [5 6 7] then the sorting index of vector A will be change [3 2 1]. In which 3 is index of 5 goes to first, 2 is index of 6 These index is arranged based on the value of A after sorting. How to do it in Matlab. For example. A=[7 6 5] S = orderfields (S1,S2) returns a copy of S1 with its fields reordered to match the order of the fields of S2. The input structure arrays S1 and S2 must have the same field names. example. S = orderfields (S1,C) matches the order of the names specified in the input array C. The name of every field in S1 must appear once in C. example To reverse a vector try the function ' wrev', here is an example: Theme. Copy. r=wrev () If you to control the degree of reverse/shifting try 'circshift' function. on 28 Jun

How do i reverse a vector - MATLAB Answers - MATLAB Central …
How can I sort a 2-D array in MATLAB with respect to one column? Sort a matrix with another matrix. I have a vector 'A' of values and a matrix 'B' of x values. Rows in A and B are share the same indices. My vector 'A' contains values but they are randomly ordered throughout the vector A がベクトルの場合、 flip (A) は、ベクトルの長さに沿って要素の順序を逆にします。. A が行列の場合、 flip (A) は、各列の要素を反転させます。. A が N 次元配列の場合、 flip (A) は、サイズの値が 1 でない A の最初の次元に対して演算を行います。. 例. B = flip 3. You can use the column operator (:) to vectorize all elements of 'nxm' matrix as a vector of 'nxm' elements and sort this vector. Then you can use direct assignement or 'reshape' function to store elements as matricial form. All you need to know is that matlab use column-major-ordering to vectorize/iterate elements: A = rand(3, 5); 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 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 An alternative to sortrows (), which can be applied to broader scenarios. save the sorting indices of the row/column you want to order by: [~,idx]=sort(data(:1)); reorder all the rows/columns according to the previous sorted indices. data=data(idx:) Share. Improve this 1 Answer. Sorted by: 2. numpy has advanced indexing, so directly use idx on both dimension will trigger advanced indexing and the result will be a 1d array; To index in a cross product fashion, you'll need to use [HOST]_ to construct the index mesh, as stated from the docs: Using ix_ one can quickly construct index arrays that will index the Also the previous note on sort wasn't so; not sure what was wrong that caused that symptom earlier 0 Comments.
