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

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.
