默认情况下,Direction 参数为“first”。 示例1: MATLAB % MATLAB code for find the index of % the elements from both directions % in the array 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==2,2,'first') 输出...
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==2,2,'first') 1. 2. 3. 4. 5. 6. 7. 8. 输出: 示例2: • MATLAB % array of integers array = [1 2 3 4 5 6 2 4 2] % find() will get the i...
To illustrate the difference in behavior, first create an array of complex numbers. A = zeros(2,1); A(1) = 1; A(2) = 0 + 1i A = 1.0000 + 0.0000i 0.0000 + 1.0000i Then create a cell array and assign the elements ofAto it. When you index intoA(1), its value is returned ...
% 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 ...
This MATLAB function applies a function func to each element of a gpuArray A and then concatenates the outputs from func into output gpuArray B.
To compute the minimum over all dimensions of an array, you can either specify each dimension in the vector dimension argument or use the "all" option. Get M2 = min(A,[],[1 2 3]) M2 = -5 Get Mall = min(A,[],"all") Mall = -5 Smallest Element Including Missing Values ...
If S is nonscalar, then getfield returns the value in the first element of the array, equivalent to S(1).field. example value = getfield(S,field1,...,fieldN) returns the value stored in a nested structure. For example, if S.a.b.c = 1, then getfield(S,'a','b','c') retu...
Each element represents a dimension of the input array. The lengths of the output in the specified operating dimensions are 1, while the others remain the same. Consider a 2-by-3-by-3 input array, A. Then sum(A,[1 2]) returns a 1-by-1-by-3 array whose elements are the sums of...
Vector of dimensions, specified as a vector of positive integers. Each element represents a dimension of the input array. The lengths of the output in the specified operating dimensions are 1, while the others remain the same. Consider a 2-by-3-by-3 input array,A. Thenprod(A,[1 2])re...
