how to printout the outputs of the clusters while doing it using the built in functions??

suppose here are the parameters

P=xlsread('NSL_KDD_TRAIN.xlsx','A2:AO125');
Q=xlsread('NSL_KDD_TRAIN.xlsx','AP2:AP125');
%cluster the dataset
T = kmeans(Q,5);
figure ;
silhouette(Q,T);
xlabel 'Silhouette Value';
ylabel 'Cluster';

how to find out those 5 clusters outputs and store them in different 5 variables?

Hi Wasima,

The "kmeans" function returns an array of cluster indices, which you can use to separate your data according to the clusters and store accordingly.

The below code snippet demonstrates how to do that:

% Perform k-means clustering
numClusters = 5;
T = kmeans(dataSet, numClusters);
% Initialize cell arrays to store cluster outputs
clusters = cell(numClusters, 1);

% Separate the data into clusters based on the cluster indices
for i = 1:numClusters
    clusters{i} = dataSet(T == i, :);
end

For more details, please refer to the following MathWorks documentation: kmeans - https://www.mathworks.com/help/stats/kmeans.html

Hope this helps!
