I am trying to find the most efficient way to get the maximum element
in a list AND its first position in the list. This is done
a few thousand times in an iteration program so any saving would
be useful. Currently I use Max and Position. For example:
x=Table[100 i^2-i^3, {i,2000}]
Timing[xm=Max[x]; Position[x,xm][[1,1]]]
Is there a way to retrieve the position by just doing Max[]
and identifying the index of the result without having to use
Position[]?
