sort! >1D array along dimension

[lucasb-eyer]

Since f4b378b, it is no more possible to sort an AbstractArray in-place along a specific dimension.

Before that commit, the necessary function for this was created by the in_place_matrix_op macro (L445). Earlier still (de7fb8b), it was implemented by calling sort! on subs of the array (R239). I hope that it's been omitted by accident and not by intent, since it's a very useful feature to have!

In any case, the documentation of sort! should be updated, since its signature still contains the [dim, ] argument but the description doesn't talk about it at all.

I'm afraid my julia-foo isn't strong enough yet to write a pull-request for this or even to decide whether just putting the implementation calling the subs back in is good enough.

The documentation for sort! has been updated.

What's the status on this? Will we support inplace sorting of other dimensions?

Once we have ArrayViews, this can be done through a view, no?

[quinnj]

Yeah, I think that's the right way forward. Let's wait till ArrayViews happen and then this can be sorted out.

@jiahao, get off of Jacob's account.

[quinnj]

Wait, what?

[kmsquire]

I think Stefan was complementing @quinnj's punny response.

[jiahao]

I feel mildly out of sorts.

I hope so, that was the main intent of this report. The documentation was just a side-issue.
