Two minutes ago I changed my mind on the source of the problem I was having: It wasn't an off-by-one error in my indexing but rather just failing to supply multiple work spaces for the case of multiple convolutions in the same PDF. D'oh! I must confess, though, that I wasn't convinced by anyone's argument, as such. So perhaps it doesn't count properly for this thread.
Admitting to being wrong isn't easy, but it's something we want to encourage.
So ... were you convinced by someone's arguments lately? Did you realize a heated disagreement was actually a misunderstanding? Here's the place to talk about it!
