index = find(array==2)输出：当数组包含重复值时，find()函数将打印相应元素的所有索引。因此，如果您不想要该元素的所有索引，则可以使用find(X,n)函数。找到（X，n）返回 X 中元素的前 n 个索引。例子：MATLAB % MATLAB code for return first % n indices of the elements in X array = [1 2 3 ...
% find() will get the index of element % gets the first index of 2 % store it in the index index = find(array==2,1) 输出: 查找(X,n,方向) 您还可以从数组中的两个方向找到元素的索引。通过使用 find(X,n,Direction),两个方向都意味着从开始和从最后开始。此函数根据方向在 X 中找到 n ...
I'm trying to find exit times from a simulation. My results are saved in an array/matrix. Each row represents the values of my 1-D random walk. I'm trying to find how long it takes on average to reach some point k. I first created a smaller arra...

Let see one more example of matlab find values in array function. In this example, we create a matrix, and then we see how matlab finds values in array works. So first, we started with creating a 2–by–2 matrix that contains random integer numbers among 1 to 4. Next, we used the...
1. 2. 3. 4. 5. 6. k= find(X,n)返回与 x 中的非零元素对应的前 n 个索引。 例子: Elements Satisfying a Condition Find the first five elements that are less than 10 in a 4-by-4 magic square matrix. X = magic(4) 1.
I have an column matrix that basically consists of NaNs and some integers in between them. Are there any functions in MATLAB that will help me find 1. the first integer value in the array, 2. its location 3. store the value Thanks, NS0...
