Accepting integer arguments for Array::range?

[nyanpasu64]

Right now I'm trying to pass integer arguments to Array::range. I have to first cast arguments to f32, then casting the result to int doesn't compile arr.mapv(|elem| elem as usize) does it work for Linspace<>?.

I noticed that range() works as I want for end<begin (unlike 5..1 which is empty). However #493 (comment) indicates I will have to perform data copies on every single range() I call, which sounds like a waste of resources.

Why doesn't Array::range and Linspace accept integer values?

• You should document numpy.astype ndarray equivalent of numpy.astype? #493 in https://docs.rs/ndarray/0.11.2/ndarray/doc/ndarray_for_numpy_users/index.html .

They are made for float arguments, use from_iter for integers.
