maximization of a function of 2 variables

I have two arrays ,

avgDistance and energy

I need to find out the array position with minimum avgDistance and maximum energy.

help me.....

I'm not sure I understand. Could you clarify if you mean that, given the minimum avgDistance, you need to find the maximum energy? Or are avgDistance and energy related and you need to find the minimum and maximum of the relational function?

You have not adequately specified the problem, because the same array position might not have both minimum distance and maximum energy.

But surely you will need the function MIN and MAX, and maybe you can figure out how to get what you want using the help files for these two functions.

ok, let me clarify it,...

I have an array of structure Snode. The Snode structure has many fields including the avgDistance and energy.

I need to find out the array index of that structure having minimum avgDistance and maximum energy.

please help...

If your structure array is consecutively numbered (e.g element 1:N), then I think this will work for you:

 [minDist   indexToMinDist]   = min([Snode.avgDistance])
 [maxEnergy indexToMaxEnergy] = max([Snode.energy])

If not, you might need to do a little bit more to find the correct index, but maybe you get the idea.
