comment A problem about recursion formula of deCasteljau algorithm
@Tangshutao But the Table construct still works, meaning (IMO) it's a bug with the syntax coloring engine.

comment A problem about recursion formula of deCasteljau algorithm
@Tangshutao It's not Global. It's localized inside of the Table function. I'm definitely not an expert in this but it appears the presence of j is made known, but no values are assigned. Table effectively uses Block so even if j had a global value assigned, the Table construct would still work as desired.

@belisarius Crazy how much improvement over Select though. Kind of disappointing for a function as prominent as it is.

comment Improving selection of elements from large multidimensional array
@belisarius @ybeltukov, My timings are very inconsistent but looks like running through a loop 10,000 times, the timings are pretty similar (maybe 10% slower using GatherBy/DownValues.
