Cannot access the function predict() in R2020b with statistics toolbox
显示 更早的评论
I cannot access the function predict() that is introduced in R2018a.,
whereas 'Statistics and Machine Learning Toolbox' is installed.
Details are as follows:
>> ver

MATLAB license number: ********
Operating system: Mac OS X Version: 10.15.7 Build: 19H2

Wavelet Toolbox version 5.5 (R2020b)
>> license('checkout','statistics_toolbox')
ans =
1
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.

Hi Pistachio,
predict ships in the System Identification Toolbox.
Thanks,
Raymond
