Is there a possible way to import such function/ packages to matlab 2023?
I try save the class after open 'kfoldpredict' function, but it seems does not work.
Thank you for possible solutions.

Hi Evelyn,
"kfoldPredict" function was introduced in r2011a. You can use the function in r2023 as well.
However, "kfoldPredict" function is a part of "Statistics and Machine Learning Toolbox". So you would need the license to the r2023 version of the toolbox.
Refer to the following MathWorks documentation to learn more about the history of the function across various versions:

How exactly are you calling kfoldPredict? The specific input arguments with which you're calling it could determine which kfoldPredict method gets called (or whether MATLAB can call that method at all!)

When you specify method 'Bag' for fitcensemble() then the output is a ClassificationBaggedEnsemble .
kfoldPredict() does not accept bagged ensembles. https://www.mathworks.com/help/stats/classreg.learning.partition.classificationpartitionedmodel.kfoldpredict.html#bsu1ryc-1_sep_mw_5cb12047-1d4f-4f41-8dfb-c81f28235bb5

I am not certain, but it appears to be that when you use Bag that the output model is not a "cross-validated partitioned classifier", so I suspect that the answer is No (at least at present.)
