Calculate absolute "distances" between each array element and the target value. % Temporary "distances" array. temp = abs (target - x); Find the minimum "distance" value by min. Compare the temporary "distances" array to that minimum value (resulting in some binary array), and then use find to get the corresponding indices, which finally can be

0. Find row in matrix, fast and with special conditions with C in matlab. See more linked questions Please help me I want to find all zero elements in matrix in MATLAB. For example, if matrix . A = [1 3 0; 2 4 9; 2 0 7] the answer should be (1,3) and (3,2). But the real matrix I want to solve is very big.
indices = find(X)indices = find(X, k)indices = find(X, k, 'first')indices = find(X, k, 'last')[i,j] = find()[i,j,v] = find() Description. [i,j] = find(X) returns the row and column indices of the nonzero entries in the matrix X. This is often used with sparse matrices. [i,j,v] = find(X) returns a column vector v of the nonzero entries in X, as well as row and column indices. In general, find(X) regards X as X(:), which is the long column vector formed by concatenating the columns of X. find (-3: 3 >= 0) find (c (0, 1, 0, 2, 3)) Example output Attaching package : 'matlab' The following object is masked from 'package:stats' : reshape The following objects are masked from 'package:utils' : find , fix The following object is masked from 'package:base' : sum [1] 4 5 6 7 [1] 2 4 5 In MATLAB it is easy to find the indices of values that meet a particular condition: >> a = [1,2,3,1,2,3,1,2,3]; >> find (a > 2) % find the indecies where this condition is true [3, 6, 9] % (MATLAB uses 1-based indexing) >> a (find (a > 2)) % get the values at those locations [3, 3, 3] What would be the best way to do this in Python? How to use 'find' function in matlab.
Por ejemplo, find(X<5) devuelve los índices lineales a los elementos de X que son inferiores a 5. Para encontrar directamente los elementos de X que satisfagan la condición X<5, utilice X(X<5).Evite las llamadas a funciones como X(find(X<5)), que utilizan innecesariamente find en una This MATLAB function performs a logical AND of arrays A and B and returns an array containing elements set to either logical 1 (true) or logical 0 (false).

While findobj has a -regexp options, not all classes support this option. This example uses the -function option to use a regular expression from a function as an alternative to the … MATLAB operators that contain a period always work element-wise. The period character also enables you to access the fields in a structure, as well as the properties and methods of an object. Examples.
In the find and replace dialog box, enter the text that you want to search for and then use the Find Next and Find Previous buttons to search forward or backward through the file. In the Live Editor and in MATLAB ® Online™ , use the and buttons or the F3 and Shift+F3 keyboard shortcuts instead.
To find the derivatives of f, g and h in Matlab using the syms function, here is how the code will look like k = find (X) 返回一个包含数组 X 中每个非零元素的 线性索引 的向量。. 如果 X 为向量，则 find 返回方向与 X 相同的向量。. 如果 X 为多维数组，则 find 返回由结果的线性索引组成的列向量。. 示例.
For instance, you can examine the even elements in a matrix, find the location of all 0s in a multidimensional array, or replace NaN values in data.
