Accessing indices and values in SparseVector

[Manoj Kumar <ma...@gmail.com>]

Hello,

This is related to one of the issues that I'm working on. I am not sure if
this is expected behavior or not.

This works fine.
val sv2 = new SparseVector(3, Array(0, 2), Array(1.1, 3.0))
sv2.indices

But when I do this
val sv2: Vector = Vectors.sparse(3, Array(0, 2), Array(1.1, 3.0))
sv2.indices

It raises an error.

If agreed that this is not expected, I can send a Pull Request.
Thanks.

Alright, thanks for the quick clarification.

When you are describing an error, you should say what the error is.
Here I'm pretty sure it says there is no such member of Vector, right?
You explicitly made the type of sv2 Vector and not SparseVector, and
the trait does not have any indices member. No it's not a problem, and
I think the compiler tells you what's happening in this case.
