how to calculate the moving maximum of a vector in matlab

To calculate the moving maximum of a vector in MATLAB, you can use the movmax function from the Signal Processing Toolbox. This function calculates the maximum value of a moving window with a specified length. Here's an example:

main.m
% create a vector of data
data = [10, 5, 8, 3, 6, 7];

% calculate the moving maximum with a window size of 3
window_size = 3;
moving_max = movmax(data, window_size);

% print the results
disp(moving_max);
206 chars
10 lines

This will output:

main.m
NaN   NaN  10.0  8.0  8.0  7.0
31 chars
2 lines

Note that the first two values are NaN because the window size is larger than the available data.

To calculate the moving maximum for each row or column of a matrix, you can use the movmax function along the appropriate dimension. For example, to calculate the moving maximum for each column of a matrix A, set moving_max = movmax(A, window_size, 1);.
