首先,创建一个空矩阵以存储所有生成的矩阵,例如:sum = []接着,假设你有一个循环生成矩阵的示例,如下所示:for i = 1:5 for j = 1:5 %假设每次循环生成矩阵为a(i,j)sum = horzcat(sum,a(i,j)) 可以把每次计算出的矩阵A保存到一个元胞结构Data中 for i = 1:n A = 你的操作; Data{i} = A...

I need to sum value in matrix but I can't use "sum". So, Can I sum value in matrix with if-else or while loop? How to create it. Assume I have matrix C=[ 1 2 3 4 5 6 7 8 9 ] Thank You How to Get Best Site Performance ...
isvector()、ismatrix() 判断是否为向量、矩阵 isempty(x)、isscalar() 判断是否为空向量、单个数值 A = [1]; U = repmat(A, 2, 3); % 结果 U = [1 1 1 1 1 1] repmat(A, 1, 2) % [1, 1] repmat(A, 2, 1) % [1; 1] 向量/矩阵初始化与生成 直接输入法:将矩阵的元素用中括...

The type ofmatrixshould be a valid MATLAB matrix or multidimensional array. For example, let’s find the sum of all the elements present in a given matrix. See the code below. m=[261;171918];sumOfElements=sum(sum(m)) In the code above, we initialize the matrixmwith values. This matr...
