af::range fails with ERR_ARG

[jramapuram]

Code:

  let dims = Dim4::new(&[128, 1, 1, 1]);
  af::print(&af::range(dims, 128, af::Aftype::F32).unwrap());

Result:

thread '<main>' panicked at 'called `Result::unwrap()` on an `Err` value: ERR_ARG', src/libcore/result.rs:731

@9prady9 : Any thoughts? I don't see anything wrong with range() in data/mod.rs

[9prady9]

@jramapuram Check the Rust doc for this function here.
C++ documentation is here

The problem is with the second argument which is a dimension specifier - takes values 0, 1, 2, 3

I just created the skeleton documentation today and will keep updating the rust wrapper documentation once we figure how to use content (as much as possible) from C++ docs in rust docs.

Assuming you wanted to create an array of size 128x128 with sequenced values along 1st dimension.
it should be the following

af::print(&af::range(dims, 1, af::Aftype::F32).unwrap());

that would give the following output

0 1 2 .... 127
0 1 2 .... 127
0 1 2 .... 127
.

.
0 1 2 .... 127

Ah! Thanks, I thought it was the initial value to start the range from.
Nice job with the docs too, will be helpful!
