How to remove column from matlab table?

Dear all,

Given table: TJClean =

    Xn_2    Xn_3    Xn_4     Prob1      Prob2      Prob3 
    ____    ____    ____    _______    _______    _______

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

Correc! removevars is only available for 2018a and beyond.

Answer 2

What about ...

TJClean(:,5) = [] 

Answer 3

[Sivabalan Selvarajan]

You can use

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