Remove outliers in matlab 2018a

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 

please help me out from this problem

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

I even tried this, that is also not working

Well, we can't infer what's wrong only from "it's not working". You need to demonstrate the problem with actual data.

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.

After trying the above code, the error is

Index in position 1 is invalid. Array indices must be positive integers or logical values.

Error in S4_index (line 64)

dset(dataout,:)= [];
