How to display citations in text grouped as [1-3] in stead of [1,2,3] [duplicate]

Citing a range of papers (using numeric keys)?

In Latex I am using BibTex for the bibliography and use `\bibliographystyle{unsrt}` to manage my references.

When I use multiple references i.e. `\cite{article1,article2,article3}` I would love to see this appear in the text as:

``````blah blah [1-3] blah blah
``````

``````blah blah [1, 2, 3] blah blah
``````

I use the format of `\bibliographystyle{unsrt}` because it numbers the references in the order they appear and would like to keep this feature but I could be flexible on which style I use.

`\usepackage{cite}` should do the trick
