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。

Array size collapse all in page Syntax sz = size(A) szdim = size(A,dim) szdim = size(A,dim1,dim2,...,dimN) [sz1,...,szN] = size(___) Description sz= size(A)returns a row vector whose elements are the lengths of the corresponding dimensions ofA. For example, ifAis a 3-...
Regular expression, specified as a string array, character vector, or cell array of character vectors.exprcan contain characters, metacharacters, operators, tokens, and flags that specify patterns to match in the property value. You can useexpronly when the property value is a string or character...
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...
