find the third moment of a data set in matlab

To find the third moment of a data set in Matlab, you can use the moment function from the Statistics and Machine Learning Toolbox. Here's an example code:

main.m
data = [1 2 3 4 5]; % example data set
m3 = moment(data,3); % compute the third moment

In this example, data is a row vector containing the data set. The moment function computes the third moment using the formula:

main.m
m3 = sum((x-mu).^3 .* w) / n

where x is the data set, mu is the sample mean, w is the sample weight (which defaults to equal weights if not specified), and n is the sample size. The output m3 is the third moment of the data set.
