Several reasons:

    1. You can use your favorite editor for writing code.

    2. Matlab-mode has a specific syntax support (like auctex does) that 
concerns keyword expansion, fontification and these sorts of things.

    3. It has a function matlab-shell that does allow you execute code, either 
the whole part or just parts of it (you have a similar feature using org mode, 
the python kernel, and jupyter, however not all commands are supported using 
org mode, plotting for example is not, debugging neither). Again a similarity 
with auctex

    4. You can debug code, although that worked better in the past, but it is 
still quite reasonable

I am not sure what you mean by interactive mode here? Do you mean that matlab 
allows you to open a specific matlab file with emacs, but configuring as an 
external editor?

If this is the case, then, you cannot debug, and you cannot execute code from 
emacs, it is more of a one way thing.

I am not sure I answered your question, I have to admit.
