But if I have the coordinates of the points in an array, I have to reshape it and then convert it into a list. Or convert it into a list and then convert it to a tuple. I know that advanced indexing is useful, but here it is not coherent. tuples and lists should have the same result on the array, or at least it should be documented.
I can't give you the reasons why that behaviour was chosen. But it's simply wrong that it's not documented. Before answering you I read the corresponding chapter in the numpy book to be sure not to tell you nonsense. So go ahead and do so, too.
So there is not way to get a sub-array based on coordinates in an array?
It's just a guess, but probably you can't use an ndarray as index because indices like this [[2],[3,4]] aren't valid input for a ndarray. Christian
