Hello, I hope you are doing well. I have the dataset,Which is wrongly clusters into 4 cluster, but there should be 3 Clusters.
The cluster 2 (cell 2) and cluster 3 (cell 3) have almost similar values. I want to rearrange the clusters to make 3 clusters
How can i do that in Matlab. Can anybody help me with that?

How are you clustering it? If you use kmeans you can tell it (force it) to use 4 clusters and it will find 4 clusters.

Your data called "clusters" has 4 datasets, so why do you say that there should be 3? When you run it, it looks like 4 clusters is reasonable. Which sets should be combined? And when you told kmeans there were 3, which sets did it combine?
s = struct with fields:
clusters: {4×1 cell}
ca = s.clusters;
plotColors = lines(numel(ca));
% Plot first 3 columns
for k = 1 : numel(ca)
thisCluster = ca{k};
plot(thisCluster(:, 2), thisCluster(:, 4), '.', 'Color', plotColors(k, :), 'MarkerSize', 40)
hold on
end
xlabel('Column2')
ylabel('Column4')
grid on

Hi, your clusters contain just matrices organized in four columns, so you can easily e.g. put two of them together (concatenate versitcally) like this:
clusters{3} = [clusters{3};clusters{4}];
And to remove the fourth cluster, you can use:
clusters = clusters(1:3);

@Jiri Hajek Let me explain this to you, I have apply clustering algorithm on this, There should be 3 Clusters, but the clustering algorithm solve this into 4 clusters
The cell 2 and cell 3 are mostly similar values, we want to apply any algorithm which have similar values or values near to each other should be in 1 cell.
