Absolutely nothing. I've never heard of them before. Are they known as something else? Here's a list of transforms. I don't see diamond transforms on there at all. Could you describe them a bit?What can you tell me about Diamond Transforms?
Perhaps I didn't use the term "transform" in a strict mathematical sense. I was more refering to the fact that as you compute a multiple integral, it reduces to a single integral, which reduces to some expression.
If we want the area between and from 0 to 1 we can either express it as,
Clearly the second reduces to the first representation. It's not a "transformation" persay.
