Hi,
I am trying to figure out how to take two arrays and make a new array with each value is the maximum value of each of the sub elements of the two arrays, i.e.
a = [5, 6, 7]
b = [3, 8, 4]
then the resultant vector would be
c= [5, 8, 7]
Ideally I would obviously like to do this without a loop!
Any help would be really appreciated

Apologies, i've just realised that max(array, dimension=2) will do what i'm after.

Well, you could do that, assuming you're concatenating your two 1D arrays in to an nx2 array. But, a more efficient way is to use the maximum operator:
c = a > b
