There's an IDE kind of environment as x0x0 mentions, but I think you're referring to the ability to mix code and text and figures all in one document? ~~MATLAB doesn't have that to my knowledge, at least not yet.~~ Strike that, there's MuPad, like the other comment mentions, though it is indeed rarely used in my experience.
Relevant to the topic at hand, Julia does have that functionality already, and it in fact (afaik) uses the same engine that's behind iPython, the Jupyter environment. There's even a web-based community version for people to try stuff out: https://www.juliabox.org/
