using for loops find the mean of rows and columns of a matrix without using the mean command in matlab

main.m
% Define a matrix
A = [1 2 3; 4 5 6; 7 8 9];

% Initialize variables for row and column wise sums
rowSums = zeros(1,size(A,1));
colSums = zeros(1,size(A,2));

% Loop through each row and column, adding up the elements
for i = 1:size(A,1)
    for j = 1:size(A,2)
        rowSums(i) = rowSums(i) + A(i,j);
        colSums(j) = colSums(j) + A(i,j);
    end
end

% Divide row and column wise sums by the number of elements to obtain means
rowMeans = rowSums / size(A,2);
colMeans = colSums / size(A,1);

% Display results
disp("Row-wise means:");
disp(rowMeans);
disp("Column-wise means:");
disp(colMeans);
