how to find the defference between elements in an array

[adamkse]

hi guys,

this is probs an easy one for you but how can you find the diffence between all elements in an array?

e.g array = 1 2 3 4 5 6

so difference between 1 and two is 1, difference between 1 and 3 is 2. all the way to trough to the differece between 6 and x is x etc.

i have been trying to use shift registers but cant quite get it.

Thanks

Try a Rotate 1-D array.  (It's in the array functions).  I think it will do just what you want.  If it doesn't, let me know.

You need to clarify your question.

Do you simply want to subtract indexes of  same array or indexes of different array.

I suppose you mean you have an array, and you want to be able to subtract one element from another element of the same array?

If that is the case, you can simply have two controls, and connect them to the index array function.

Thanks for the fast replys guys.

to try and clarify what I am wanting to do: I want to subtract one element from all others then move to the next element then subtract all others, all the way though to the end. This is all within the same array.

Harold's idea was close but only works for the first element.

you could replace my constant in the index array with a control and step through the array and it should subtract properly

No need for the outer loop.
