Remember that x[i] applies the index array i to the first axis of x.
In order to apply i to the second axis, you need an argument in the
first position, too, to give the indices that apply to the first axis.
Remember that the arguments will be broadcast against each other.
In : x[ [,], x.argsort(1)]
