Let’s say I want to find the position of the maximum element in a 2D array. The closest I found: [`indmax`

] (https://stackoverflow.com/a/37474579/2338725) or `findmax`

,

which does not work as expected with arrays having more than 1D:

```
julia> x = [8 -4 3; 1 10 -1; 3 12 4]
3×3 Array{Int64,2}:
8 -4 3
1 10 -1
3 12 4
julia> indmax(x)
6
julia> findmax(x)
(12,6)
```

As position, it returns one integer, `6`

. Of course, from this, we can compute the 2D coordinate `(3,2)`

. But, wouldn’t it be nice to see the 2D coordinate as output directly? Is it worth reporting an issue?

```
julia> x = [[8 -4 3], [12 10 -1]]
2-element Array{Array{Int64,2},1}:
[8 -4 3]
[12 10 -1]
julia> indmax(x)

```

- Is this worth reporting a bug? Or, I misunderstood anything?
- For 1D array, both
`indmax`

and`findmax`

return a 2 element array, the second element being the position. Depending on the situation, which may not be sufficient (e.g., to find the frequency of the maximum element; find the maximum element along one particular axis).`Numpy`

provides a lot of functions:`argmax`

,`max`

or`amax`

,`maximum`

,`argsort`

etc. Wouldn’t it be nice to have these features?[/details]
