how to calculate the moving sum of a vector in matlab

To calculate the moving sum of a vector in Matlab, you can use the conv function with a window of ones. Here's an example:

main.m
% Define vector and window size
vec = [1 2 3 4 5];
window_size = 3;

% Calculate moving sum using convolution
window = ones(1, window_size);
mov_sum = conv(vec, window, 'valid');

% Display result
disp(mov_sum);

In this example, we define a vector vec and a window size of 3. We then create a window vector of ones using the ones function. Finally, we use the conv function with the 'valid' option to compute the convolution of the vec and window vectors, effectively computing the moving sum. The resulting vector is then displayed using the disp function.
