Reading the documentation of
Position, I found there's a possible issue:
Position looks for matches based on patterns, which may not be the same as numerical equality:
Position[Range[-1, 1, 0.05], 0.1]
Then a possible way to fix this is left
Position[Range[-1, 1, 0.05], n_ /; n == 0.1]
My question: Is there a way to fix this issue when you have a list of lists? Because I tried something like the above and it didn't work.
