add column 1 and column 2 of a matrix in matlab

To add column 1 and column 2 of a matrix in MATLAB, you can use column-wise indexing and addition operation. Here's an example code that demonstrates this:

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

% Add column 1 and 2
sum_col_1_2 = A(:, 1) + A(:, 2);

% Display the result
disp(sum_col_1_2);
148 chars
9 lines

In this code, we first create a sample matrix A. To add column 1 and 2, we use column-wise indexing to select these columns (A(:, 1) and A(:, 2)) and then use the addition operation to add them together. The result is stored in the variable sum_col_1_2. Finally, we display the result using the disp function.
