1. write a matlab script that calculates matrix addition – use for loops. in matlab

To write a MATLAB script that calculates matrix addition using for loops, you can follow these steps:

1. Declare two matrices, A and B, with the same dimensions.
2. Initialize an empty matrix, C, with the same dimensions as A and B, to store the result of the addition.
3. Iterate over each element of A and B using for loops.
4. Add the corresponding elements of A and B and store the result in the corresponding element of C.
5. Display the matrix C as the result of the addition.

Here's an example MATLAB script:

main.m
% Declare the matrices A and B
A = [1 2 3; 4 5 6; 7 8 9];
B = [9 8 7; 6 5 4; 3 2 1];

% Get the dimensions of A and B
[m, n] = size(A);

% Initialize the matrix C
C = zeros(m, n);

% Perform matrix addition using for loops
for i = 1:m
    for j = 1:n
        C(i, j) = A(i, j) + B(i, j);
    end
end

% Display the result matrix C
disp('Matrix Addition Result:');
disp(C);

This script declares two matrices A and B, performs the element-wise addition using nested for loops, and displays the resulting matrix C.

Note that MATLAB also provides a built-in element-wise addition operator (+) for matrices, which can perform the same calculation without the need for explicit for loops.
