I recently posted a question asking about the convergence behavior for a Mathematica algorithm Thinning https://dsp.stackexchange.com/questions/10667/what-does-convergence-mean-for-thinning, and I quickly recieved comments that the question was off-topic. It was then migrated to dsp.stackexchange.com.
All of this is fine, I'd just like to understand what happened? Right now I'm feeling like I committed some kind of faux pas.
The justification I have for asking the question is that, to my understanding, and I could be wrong, the function Thinning isn't something like FourierTransform. It's a specific image processing procedure that I've only seen in Mathematica, and I was inquiring about what a line meant on convergence for the function description.
