array = [1 2 3 4 5 6 2 4 2]% find() will get the index of element % store it in the index 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...
[row,col,V] = find():返回包含非零元素的向量 V 现在让我们看看如何在示例的帮助下使用find()函数查找数组中任何元素的索引。 找到(x) find(X) 返回一个向量,其中包含 数组 X 中每个非零元素的线性索引。 示例1: MATLAB % MATLAB code for find an index of any % element in an array using the ...
index = find(array==2,2,'last') 输出: [行,列] = 查找(x) 要在3 维数组中查找元素的索引,您可以使用语法[row,col] = find(x)这将为您提供元素所在的行和列。 例子: MATLAB % MATLAB code for Finding an index % of an element in a 3-D array array = [1 2 3; 4 5 6; 7 8 9] ...
% element in an array using the find() array = [1 2 3 4 5 6] % find() will get the index of element % store it in the index index = find(array==3) 1. 2. 3. 4. 5. 6. 7. 输出: 注意:如果数组包含重复项,则 find(X) 函数将返回该整数的所有索引。 示例2: • MATLAB % ...
i have to find the index of the same value in an array,see the following example a=[1 2 3 1] i want b=[1 4] as output..how can i do this? A solution using find is this u=unique(a) n=histc(a,u) find(a==u(n>1)) ...
Given two array Idx_of_pt and P, I'd like to find all the row element in P from Idx_of_pt Idx_of_pt=[1 2 3;4 6 7;2 3 5]; P=[-0.03 0.12 0.04 -0.94 0.12 0.01 -0.06 0.15 0.037 -0.22 0.13 0.02 -0.26 0.12 0.07
Find the nonzero elements in a 3-by-3 matrix. X = [1 0 2; 0 1 1; 0 0 4] 1. X =3×31 0 2 0 1 1 0 0 4 1. 2. 3. 4. 5. k = find(X) 1. k =5×11 5 7 8 9 1. 2. 3. 4. 5. 6. 7. Use the logicalnotoperator onXto locate the zeros. ...
Therefore, if we consider only the firs index of A, i.e. either A{1} or A{2}, my Result would be something like: 테마복사 Result = 2x1 logical array 1 0 Which means my 'BLUE' text is in A{1}. My first attempt started by using 'strc...
ind = 1x6 logical array 0 0 1 0 0 1 Suppose you want to find the values of the elements that are not missing. Use the ~ operator with the index vector ind to do this. Get strvals = str(~ind) strvals = 1x4 string "A" "B" "D" "E" For more examples using logical ind...
我们需要使用cellfun函数，或者用间接的方法：把cell的索引组成一个和cell形状相同的array，如下output=...
