Part of it is me inheriting a legacy code base and part of it is the fact that it is easier to collaborate with members of my field using MATLAB as it is common knowledge. Python is fine, but I do like having matrices as first-party language members -- that's just a nitpick though. I'm starting a new project soon that I intend to do in Julia because it seems to have everything I like from Python and MATLAB combined.
