There is
maximum(A, 3)
but I gather you also want the index? If so, mapslices is your best one-liner
as of now. But if you're performance-sensitive, you might also look into this:
M = maximum(A, dims)
ismax = A .== M
and then find the `true` elements of ismax. I'll bet that's quite a lot faster
than using mapslices, even though it requires two traversals of the array. As
a bonus, you'll also learn about ties.
