From: Frank Sabouri on 1 Jan 2010 23:36 Hi: There is a matrix that is "x" [different conditions (168)-by-variables (9)]. You suppose that I made 28 different sub-matrices from "x", wherein size of each sub-matrix is (6-by-9). I want to compute Euclidean distances among 9 variables for any given sub-matrix. X (:,:,:)=subdivide (x,6,9); % size of cell is (6,9,28) for i = 1:28, [Y] = pdist (X(:,:,i)'); Ym=mean (Y) ; Z=linkage(Ym,'average'); end May please somebody show me where the problem is. Thanks, Frank

The loop cycles through different values of i and you will want to assign the output of each time you run the loop to a different variable or a different spot in the output matrix. For example, P(i,1:10)=Z; Regards! Matt

Please let me know if it is what I should do. for i = 1:28, [Y] = pdist (X(:,:,i)'); P(i,1:28)=28; end Ym=mean (Y) ; Z=linkage(Ym,'average'); Regadrs, Farnk |
