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.
