MATLAB: Parameter manipulation in naive bayes classificator struct

MATLABnaive bayesStatistics and Machine Learning Toolbox

Is it possible to manipulate the parameter of a naive bayes structure createt by NaiveBayes.fit()? I've tried, but it didn't work:

EDU>> cls.prior = [0.5 0.5]
Error using NaiveBayes/subsasgn (line 9)
The NaiveBayes class does not support subscripted assignments.

You can change the prior before the model is fit. If you want to specify different prior, you can do that while calling NaiveBayes.fit or fitNaiveBayes function using the name value pairs:

"training" is used to train a classifier (pass it to FIT method), and "sample" is used to test the classifier performance on data not used for training (pass it to PREDICT method). for example:

O1 = NaiveBayes.fit(training,group);
C1 = O1.predict(sample);
cMat1 = confusionmat(sampleGroup,C1);

where sampleGroup is an array of true class labels for the predictor matrix in "sample".

In this Doc section https://www.mathworks.com/help/stats/fitcecoc.html?searchHighlight=fitcecoc&s_tid=doc_srchtitle#d117e320264,

it says

"The optimization attempts to minimize the cross-validation loss (error) for fitcecoc by varying the parameters. For information about cross-validation loss in a different context, see Classification Loss. "

If you click on "Classification Loss" it tells you about the multiclass loss function.
