(min/max)_axis(_skipnan) #68
Description
A common use case for me is taking the min or max over one axis of a multidimensional array, much like quantile_axis_mut, except I don't want to mutate my original data and I don't need the overhead of tracking quantiles. I couldn't find mentions of this idea in other issues. Will you consider a PR for such methods?
I was thinking along the lines of
pub trait QuantileExt<A, S, D>
where
S: Data<Elem = A>,
D: Dimension,
{
fn min_axis_skipnan(
&self,
axis: Axis,
) -> Array<A, D::Smaller>
where
D: RemoveAxis,
A: Ord + Clone + MaybeNan,
A::NotNan: Ord;
}

I would also find this useful. I'm currently using something like:

Given that the
skipnanfunctionality is not available inndarrayitself I'd say that this would be a good addition for convenience 👍
