I like Juno for that: http://junolab.org/

It will take awhile for it to fully utilize v1.0. Remember, it just came out so packages will need to catch up. The debugger for example needs to be updated, along with the plotting packages and such. But once everyone updates it should give a very similar experience.

While Jupyter is not technically an IDE, I've found it a more than adequate replacement for the MATLAB environment. When I used MATLAB, I didn't often need to use the debugger, so the "IDE" that I actually use/need is mainly just an integrated REPL and code editor. Jupyter serves that purpose and also has the benefit of providing a very literate history of your research

There's Juno [1], works great.
