07 Jul 2009 EM_GM An expectation maximization algorithm for learning a multi-dimensional Gaussian mixture. Author: Patrick Tsui Athavale, Yashodhan

I have a multidimensional file in Microsoft Excel. I imported the sheet into X, and executed [W,M,V,L] = EM_GM(X,3,[],[],1,[]);

I am getting the following errors,

[W,M,V,L] = EM_GM(X,1,[],[],1,[])
Warning: Ignoring rows of X with missing data.
> In kmeans at 127
  In EM_GM>Init_EM at 261
  In EM_GM at 74
??? Attempted to access C(1,2); index out of bounds because numel(C)=1.

Error in ==> kmeans>distfun at 722
            D(:,i) = D(:,i) + (X(:,j) - C(i,j)).^2;

Error in ==> kmeans at 329
    D = distfun(X, C, distance, 0);

Error in ==> EM_GM>Init_EM at 261
[Ci,C] = kmeans(X,k,'Start','cluster', ...

Error in ==> EM_GM at 74
    [W,M,V] = Init_EM(X,k); L = 0;

Please Help....!!! thanks in advance..... :)

it's very helpful thanks

it might be also any other implementation of netlab. type edit kmeans to find the culprit one.

When I run [W,M,V,L] = EM_GM(X,3,[],[],1,[]); on matlab command as the example, the error happened, as below:

??? Error using ==> kmeans.kmeans
Too many input arguments.

Error in ==> EM_GM>Init_EM at 305
[Ci,C] = kmeans(X,k,'Start','cluster', ...

Error in ==> EM_GM at 63
    [W,M,V] = Init_EM(X,k); L = 0;

Please help,thanks
