[英]Sum of elements in matrix using sum function by matlab
I have 3 matrices which have similar size. 我有3个大小相似的矩阵。 I want to calculate sum of all matrices element by element. 我想逐个元素地计算所有矩阵的总和。 How to implement it by matlab using sum function? 如何使用sum函数通过matlab实现它? And If I want to sum only first and third matrix without second matrix, how to do it -Note that my number of matrices can be more than 10? 如果我只想在没有第二个矩阵的情况下求和第一个和第三个矩阵,那该怎么做 - 我的矩阵数可以超过10个? This is my matrix 这是我的矩阵
A(:,:,1)=randint(5,5,10);
A(:,:,2)=randint(5,5,10);
A(:,:,3)=randint(5,5,10);
% Output look like
B=A(:,:,1)+A(:,:,2)+A(:,:,3);
%% How to use sum function for above task
%% If I want to sum only first and third matrix, how to do it?
尝试sum(A,3)
沿第三维求和,如果你想省略某些“矩阵”,那么只需使用正态索引:
sum(A(:,:,[1,3]),3)
