How to list top 3

Hello

I want help

Data = readmatrix('brain_liver.csv');
%normalization
for i = 1:12 
   Datanorm(:,i)  = Data(:,i) .* 100/max(Data(:,i));
end
S = std(Datanorm,[],2);
%dimension
Max = maxk(S,3);



%Index from 3 tops
%  Line : 12 30 44 

From my code I find S from data norm and list top 3 in Max

I want to list top 3 in datanorm ranking from S

How can I do that

Thx

Data = readmatrix('brain_liver.csv');
Datanorm = Data .* 100 ./ max(Data, 1);
S = std(Datanorm,[],2);
[Max, MaxIndex] = maxk(S,3)

Thx for your help but I want it to show all data in row 12 ,33 and 44

Do you mean:

Datanorm(MaxIndex, :)

[Phudit Kanittasut]

MaxIndex is show the row of the data which I need So I want to show only the Datanorm value only from Maxindex value

I do not understand, what these screenshots should tell. You have a matrix and the indices. Then why does indexing the matrix not solve the problem? What exatcly does "only the Datanorm value only from Maxindex value" mean? Can you give a small example?
