Hello,

I have a matrix contains 5 columns,

I want to remove the outliers from the 5th column using matlab 2018a and then same should be removed from the other four columns also

Now i am using

dset = Final_roti ; %data with 5 columns
dataout = removeoutliers(dset(:,5));
dset(dataout)= []; % this is not working

You've presented a solution already. What help is needed?

dset(dataout)= [];

this is not working.

I mean removing from all other columns is not working.

Perhaps as follows:

A=repmat((1:5)',1,5); A(end-1)=100,
A = 5×5
     1     1     1     1     1
     2     2     2     2     2
     3     3     3     3     3
     4     4     4     4   100
     5     5     5     5     5
tf=isoutlier(A(:,5));
A(tf,:)=[]
A = 4×5
     1     1     1     1     1
     2     2     2     2     2
     3     3     3     3     3
     5     5     5     5     5

What does "does not work" mean in this context?

Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support so we can investigate.

Please show us a small sample of data, show us what steps you perform to try to remove outliers from that data set, show us the results you received, and tell us what results you expected to receive and why. And no, your original message is not sufficient for this purpose; we have no idea what data your Final_roti variable contains.
