how to add multiple matrices in matlab

To add multiple matrices in Matlab, firstly, ensure that all matrices have the same dimensions. Then, you can use a loop to iterate over each element of the matrices and add them together. Here is an example code snippet:

main.m
% Define matrices
A = [1, 2, 3; 4, 5, 6; 7, 8, 9];
B = [9, 8, 7; 6, 5, 4; 3, 2, 1];
C = [2, 2, 2; 2, 2, 2; 2, 2, 2];

% Initialize output matrix
output = zeros(size(A));

% Loop over matrices and add them
for i = 1:size(A, 1)
    for j = 1:size(A, 2)
        output(i, j) = A(i, j) + B(i, j) + C(i,j);
    end
end

% Display output matrix
disp(output)
352 chars
18 lines

In this example, matrices A, B, and C are added together using nested loops to iterate over every element in all three matrices. The resulting matrix is then stored in the output variable and displayed using the disp command.
