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 ...
Minimum elements fromAorB, returned as a scalar, vector, matrix, multidimensional array, table, or timetable. The size ofCis determined by implicit expansion of the dimensions ofAandB. For more information, seeCompatible Array Sizes for Basic Operations. ...
array = [1 2 3 4 5 6 2 4 2]% 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...
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 min(A,[],[1 2]) returns a 1-by-1-by-3 array whose elements are the ...
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: 示例2: MATLAB % array of integers array = [1 2 3 4 5 6 2 4 2] % find() will get the index of element % store it in the index...
Let's take a simple example to illustrate the concept of cell arrays. Suppose I have a cell array cell, which contains four elements: the first element is a real number 100, the second element is a vector [1, 2; 3, 4], the third element is a text 'Hello', and the fourth element...
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...
S = sum(A,vecdim) sums the elements of A based on the dimensions specified in the vector vecdim. For example, if A is a matrix, then sum(A,[1 2]) returns the sum of all elements in A because every element of a matrix is contained in the array slice defined by dimensions 1 and...
C=2×3 cell array{'first'} {'second'} {'third'} {[ 1]} {[ 2]} {[ 3]} 如果数组中的元胞包含数值数据,可以使用cell2mat函数将这些元胞转换为数值数组。 numericCells = C(2,1:3) numericCells=1×3 cell array{[1]} {[2]} {[3]} ...
S = sum(A,vecdim)sums the elements ofAbased on the dimensions specified in the vectorvecdim. For example, ifAis a matrix, thensum(A,[1 2])returns the sum of all elements inAbecause every element of a matrix is contained in the array slice defined by dimensions 1 and 2. ...
