Hello,

If I have two N-by-N matrices A and B, how can I find the N-by-by matrix C such that its (m,n)th element is the max of the (m,n)th element in A and the (m,n)th element in B?

Note: I don't want to use a for loop because N is quiet large.

Thanks

Nicely done I think I over-complicated this :)

If I have two vectors of dimension (X,1) and (Y,1). I want to compare (x1,y1), (x2,y2) and so on and store the larger number in another vector. How to do this?
