could anyone help me how to change the number of clusters for every iteration

I am having an array of data set A=[1 2;

3 4;

5 6;

7 8;

9 10;

11 12]

I want to group A into different number of clusters under the condition the number of clusters should not be more than size(A,1)

I need to run for several iterations.

For every iteration the number of clusters needs to be changed.

A=[1 2;
3 4;
5 6;
7 8;
9 10;
11 12] ;
G = size(A,1) ;
idx = cell(G,1) ;
for i = 1:G
    idx{i} = kmeans(A,i) ;
end

ok.

But what i actually need is the number of clusters needs to be changed for each iteration which means the result needs to be displayed in the following manner.

for example if it is 2 clusters then it should be as{(1 2),(3 4),(5 6),(7 8)} and {(9 10),(11 12)}-iteration1

for 3 clusters {(3 4),(5 6),(1 2)},{(7 8),(9 10)} and {(11 12)}-iteration 2

for 1 clusters {(1 2),(3 4),(5 6),(7 8),(9 10),(11 12)}-iteration 3

for 4 clusters{(5 6),(7 8)} {(9 10)} {(3 4),(11 12)} {(1 2)} -iteration4

The number of clusters need not be fixed for each iteration.

Could you please help me on this.

YOu have the inidces in hand.....you shoul dbe able to do it.

the indices are not determined by itself,for example i had given it

but the code needs to determine by itself.

What do you think these lines do?

for i = 1:G
    idx{i} = kmeans(A,i) ;
end

Those lines are meant for grouping the data set into clusters in a successive manner

first all are grouped into 1 cluster.

then 2 clusters,3 clusters ..................8 clusters.

But what i need is for one iteration the dataset needs to be grouped either in 1 or 2 or 3 or 4 or.......8.

for example if data set are grouped into 2 clusters during 1st iteration,it can be grouped into different number or same number of clusters in second iteration.
