I am trying to remove a column from a matlab table(not a matrix) with the next codes:
%remove one for the last column TJNew= removevars(TJClean,5); TJNew= removevars(TJClean,'Prob2'); TJNew= removevars(TJClean,TJClean.Prob2);
but I am getting this error: Undefined function or variable 'removevars'.
What am I doing wrong? Can somebody give me a suggestion?
Thank you in advance!

Try:
TJNew= removevars(TJClean,{'Prob2'});
If it doesn’t work still tell which version of matlab you are using
I suspect it’s available only from 2018a
So you can do
TJClean.Prob2=[] %this will remove the specified column

What about ...
TJClean(:,5) = []

You can use
TJClean( : , end-1 ) = [ ] ;
