how to calculate the moving percentile of a vector in matlab

To calculate the moving percentile of a vector in Matlab, you can use the function movpercentile from the Statistics and Machine Learning Toolbox. The function calculates the specified percentile of a sliding window of elements in a vector. Here's an example code block:

main.m
% Create a vector of data
data = [10, 11, 12, 13, 14, 15, 16, 17, 18, 19];

% Set the window size
window_size = 5;

% Calculate the 50th percentile for each window
percentiles = movpercentile(data, window_size, 50);

% Display the results
disp(percentiles);

In this example, we first create a vector of data, data, that we want to calculate the moving percentile for. We then set the window size window_size to 5, which means the function will calculate the percentile of every 5 consecutive elements in the vector. Finally, we call the function movpercentile with the arguments data, window_size, and 50, which calculates the 50th percentile of each window. The result of this operation is stored in the variable percentiles, which we then display using the disp function.
