how to calculate the moving range of a vector in matlab

To calculate the moving range of a vector in Matlab, you can use the movrange function from the Statistics and Machine Learning Toolbox.

Here's an example code block that calculates the moving range of a vector x:

main.m
% Generate a sample vector
x = [4, 7, 1, 9, 2, 8, 3];

% Calculate the moving range with a window size of 3
mr = movrange(x, 3)

% Output:
% mr =   NaN     6     8     8     7     7     6

In this example, the moving range is calculated with a window size of 3, which means that the range is calculated for every three consecutive elements in the vector. The output is a vector of the same size as the input vector, where the first two and last two elements are NaN because the window size extends beyond the edges of the vector.
