Clojurians Log v2

I would use something like:

(let [m [[1 2] [3 4]] max (emax m)] (filter #(= max (apply mget m %)) (index-seq m)))

Would be more efficient to do this with something like ereduce-indexed but we haven't implemented that yet 🙂

yeh I'm using index-seq but that's linear & I was hoping for a logarithmic solution - like, if the matrix were stored as a tree

your fn is shorter than mine though so I'll use it 🙂

i was doing the reduce - though interestingly according to criterium they're almost exactly the same
