Quote from Rahula Gautama:
Incapable of explaining to YOU, you innumerate cretin!
I'm not the innumerate cretin, you moron.
I have a minor in mathematics, so there isn't anything mathematical you couldn't explain to me.
You are delusional if you believe anybody could understand the gibberish you have used to describe your charts and graphs.
There is no explanation, other than reference to mathematical methods of Infinite Impulse Response that are unintelligible. So with the OP not knowing english well and not willing to reveal the actual math, ie:hint to the op, looking at your code should enable a concise explanation, there isn't anymore discussion here than "Look what I found! Another useless acronymical math snippet of Jack Hershey's method!"
