Clusters lables for fuzzy c mean

Hi,

I have used MATLAB code for fuzzy c mean clustering :

X= data set.
[centers,U] = fcm(X,3)
labels = ones(size(X,1),1);  
for i = 1:size(X,1) 
    aux = U(i,:);  
    [elem,index] = max(aux);  
    labels(i,1) = index;   
end 

but I have an error which is :

Index exceeds matrix dimensions

Error in FCMtest (line 27)

aux = U(i,:);

Please could you determine where is the issue ?

whos X
whos U

What do you see in the command window?

Whos U

Name Size Bytes Class Attributes

U 3x1363 32712 double

---------------------------------------------------------------------

Whos X

Name Size Bytes Class Attributes

X 1363x2 21808 double

------------------------------------------------------------------------

How can we solve this issue, i can not change U ?

Replace

for i = 1:size(X,1) 
    aux = U(i,:);  
    [elem,index] = max(aux);  
    labels(i,1) = index;   
end 

with

[~, labels] = max(U, 1);

[shawin]

Error using max

MAX with two matrices to compare and two output arguments is not supported.

Error in FCMtest (line 15)

[~,labels]=max(U,1);

[Walter Roberson]

[~, labels] = max(U, [], 1);
