What kind of LDA performs 'fitcdiscr' function?

Hi all,

I know that the new 'fitcdiscr' MATLAB® function (https://es.mathworks.com/help/stats/fitcdiscr.html) can perform several discriminant analysis, such as LDA or QDA. However, the mentions about 'regularization' and 'bayesian' inside the MATLAB® help confuse me.

What kind of discriminant analysis is performed if 'fitcdiscr' uses the default parameters? Do it use Bayesian Linear Disciminant Analysis (BLDA), Fisher's LDA (FLDA), or some kind of Regularized LDA (rLDA)?

Thanks in advance, Víctor.

By default, it does 'Linear' LDA and description of 'Linear' tells that its is some kind of Regularized LDA (rLDA). See screenshot of MATLAB documentation
