fortran question

[dimosaaaa]

hello,hello!
Is there any expression in fortran, in order to find the two points which have more closely their coordinates?
thanks?

Sorry, what is your question ??
Which points are meant ? On teh screen ? In outer space ?

The optimist believes we live in the best of all possible worlds - the pessimist fears this might be true.

do YOU know the expression to find the distance between two points? Well, for starters, you could write a couple of nested do loops and evaluate the distance between all possible pair of points...welcome to programming.

There is non-trivial algorithm O(n*log n) solving this problem. It's far from "any expression" level code (search Google for nearest neighborn problem).

Brute force method O(n*n) - see salgerman's post above
