A is my array of numbers
I substract all the elements from each other with A - A' which give me a matrice T with size of length (A) * length (A)
Now that I want to look for specific value in this matrice, find (T == x) it gives me the indices of the value in the matrice.
My question is how can I find out what this indece represents in form of my initial array A?
in short :::
T = A - A '
find (T == my value) ==> ans = i where T (i) == my value
how to find out j and k where T (i) = A (j) - A (k)
Thanks in advance!
