splitting data based on cluster indices

Hello so I have customer data where I used kmeans clustering. It partitioned the data into 4 different clusters. If I have customer ids A = [1:1600] and the cluster indexes for each of theses 1600 customer ids. How can I separate the data so that I can view which customers are in each of the specific clusters.

results = cell(4,1);
for K = 1 : 4
  results{K} = A( cluster_indices == K );
end

cluster indices would be IDK value from [IDK,C,sumd,D] = kmeans , so I should write results{K} = A(IDK == K}?

Yes.
