Hm that limitation sounds severe! Functions are essential. I actually don't remember that, but I last used MATLAB like 15 years ago! I've done a lot more data science than linear algebra in the last decade. It sounds like RStudio might be a better model for what we want: https://en.wikipedia.org/wiki/RStudio https://en.wikipedia.org/wiki/RStudio (click on the screenshot) It only works with R, but a lot of people say great things about it. I saw another commenter say that Jupyter is more like Mathematica notebooks, and RStudio is more like MATLAB. I think this sounds right. In the former, the interactive experience is more central. In the latter, you are developing a program, and the IDE helps you do it interactively. But the program is central. (At least this is true for R, it sounds like it might not be as true for MATLAB. But I know that pretty large programs are written in MATLAB.) For now I'm still sticking with my highly-custom shell-based workflow. But I do want to make interactive graphics less painful. Right now I juggle a web browser, a terminal, a text editor, and an R REPL!
