I cannot access the function predict() that is introduced in R2018a.,

whereas 'Statistics and Machine Learning Toolbox' is installed.

Details are as follows:

However, '>> which predict -all' returns negative.

Who can tell me why I cannot use predict() function?

'predict.m' file is found in MATLAB_R2020b.app > toolbox > stats > classreg > +classreg > +learning > +svmutils > +gpu,

and the code is shown as '% GPU entry point for the SVM predict mex function.'.

How are you calling the predict()? Note that in statistical and ML toolbox, predict() is defined as a method, rather than an independent function. So it will not automatically be shown by which -all (It will be shown if the object containing this method is loaded in the workspace). It will only be called if the first input is a model object, e.g., linear model from the toolbox.
