Hi ,

I have an array of Array(dimension of 10x12000) size. In one plot I want to show All the 10 rows element. I used simple plot(ArrayName). but i am not able to classify the points. Is there any function so that it can create 10 different clusters??

regards

Yes i used K means. I just want to draw those clusters in one figure. I used silhouette function and got histogram kind of clusters. I need like 10 different circles kind of image

I don't understand. Attach a picture of what you'd like to achieve.

I’m not certain what you want to do, but if you just want to plot your matrix, something like this may work:

N = 100;                                % Replace With 12000
A = rand(10, N);                        % Replace With Your Data
D = A + repmat([1:10]', 1, N);
X = [1:100];
figure(1)
plot(X, D)
grid

It offsets your data in ‘D’ so that they will plot essentially separately, depending on the offset. I chose offsets of 1 here (the [1:10]' vector). Choose the offset that works with your data.

Run my code first to see how it works, and if it seems to do what you want.
