I am asking what logic did you follow to get that output from that particular input.

How do you define minimum difference?

I take this to mean the three elements of X with the smallest extreme spread. I don't see that pdist2() would work for that.

This might work, so long as the number of elements in X stays small.

X = randi([0 99],3,3)

C = nchoosek(X(:),3);

Crange = range(C,2);

row = Crange == min(Crange);

C(row,:)

From what's given, there's no reason to think that there's a unique minimum combination. The first example @Dyuman Joshi gave is a good demonstration. The example I gave will return all combinations with the same minimum spread.

I still don't understand. How does a 3x3 array have 12 elements, and where does 4 come in?

Are you trying to find the minimal combinations left in X after removing each minimal combination?
