MATLAB: What is the toolbox for kmeans

kmeanskmeans problem function

What is the toolbox to obtain kmeans as a function? I have these toolboxes: 'Deep learning toolbox, Statistics and machine learning toolbox, Image processing toolbox', but Matlab doesn't find kmeans as a function. Why??

Best Answer

The kmeans function is in Statistics and Machine Learning Toolbox (previously the Statistics Toolbox) and has been since at least release R2006a. Do you have this toolbox both installed and licensed? [If you're in an environment where you share licenses with others in your institution, all the licenses may be in use when you try to use kmeans.]

Can you clarify what you mean by "Matlab[sic] doesn't find kmeans as a function"? Does it throw an error (and if so what is the full and exact text of that error -- show us all the text displayed in red?) Does it issue a warning? Does it do something else?

Your ‘T’ matrix must become a cell array. See my sample of ‘T’ for an example.

Once you do that, I would do something like this:

Y = [12.004
    13.1573 
    11.1665  
    11.8082    
    12.2129   
    12.8075   
    12.4167  
    11.5708   
    12.5798    
    13.7489];
T={'cluster2'; 'cluster1'; 'cluster3'; 'cluster9'; 'cluster0'; 'cluster7'; 'cluster4'}; % Sample Of Cell Array
[UnqClust,~,idx] = unique(T);                                                           % Unique Values & Locations
Out = Y(idx);                                                                           % Mapped Output
for k1 = 1:length(idx)
    fprintf(1, '\t%s\t%.4f\n', T{k1}, Out(k1))              % Demonstration Output (Delete Loop)
end
  cluster2  11.1665
  cluster1  13.1573
  cluster3  11.8082
  cluster9  12.4167
  cluster0  12.0040
  cluster7  12.8075
  cluster4  12.2129

This code might do what you are looking for

ix = sscanf( T(:,end), '%1d' );
Y  = cat( 1, Y, rand );     % add one element to get 10
R  = Y(ix+1);

inspect the result

>> R(1:6)'
ans =
   11.1665   11.1665   11.1665   11.5740   11.5740   11.5740

where

T=['cluster2'
'cluster2'
'cluster2'
'cluster7'
'cluster7'
'etc ....'];
