MATLAB: Question on the lasso example in matlab documentation

lassooptimization

In the Lasso documentation page here: https://www.mathworks.com/help/stats/lasso.html
Construct the default lasso fit.
B = lasso(X,y);
Find the coefficient vector for the 25th Lambda value in B.
B(:,25)
Is there any particular reason why the 25th lambda value in B was chosen? I don't understand this part. Thanks

Best Answer

The example is just intended to show how to use the function. I wanted to show what the output looked like, that the coefficient corresponding to a particular lambda value is a vector. I chose 25 arbitrarily. Sorry that it confused you.
