Categorical Function Fails: Matlab 2019a

I just installed MATLAB 2019a and it seem that the "categorical" function not work. Now even on the MATLAB example.

I get the following error:

Undefined function 'categorical' for input arguments of type 'cell'.

which categorical

returns

/Applications/MATLAB_R2019a.app/toolbox/distcomp/parallel/@codistributed/categorical.m % codistributed method

My code works with no problem in MATLAB 2018b. Here

which categorical 

returns

/Applications/MATLAB_R2018b.app/toolbox/matlab/datatypes/@categorical/categorical.m % categorical constructor

Would an one know what's going on here?

Thanks

Try with the -all option

which -all categorical

just to see what it says...

Seems hard to imagine such would have passed pre-release QC checks if isn't something munged in the distribution/download/install process...

I presume you have tried a restart and the symptom remains?

Thanks dpb.

which -all categorical

only returned two categorical.m locations.

/Applications/MATLAB_R2019a.app/toolbox/matlab/bigdata/@tall/categorical.m % tall method

/Applications/MATLAB_R2019a.app/toolbox/distcomp/parallel/@codistributed/categorical.m % codistributed method

Whereas MATLAB 2018b returns three categorical.m files

/Applications/MATLAB_R2018b.app/toolbox/matlab/datatypes/@categorical/categorical.m % categorical constructor

/Applications/MATLAB_R2018b.app/toolbox/matlab/bigdata/@tall/categorical.m % tall method

/Applications/MATLAB_R2018b.app/toolbox/distcomp/parallel/@codistributed/categorical.m % codistributed method

So I looked inside the MATLAB 2019a Application Installation file and found a third categorical.m file in the datatypes/@categorical/ folder, which for some reason unknown to me MATLAB 2019a could not read.

From here, I just reset the search path and now ALL IS FINE.

Thanks once more.
