TITLE: What programming languages do mathematicians use?
QUESTION [68 upvotes]: I understand this might be a slightly subjective question, but I am honestly curious what programming languages are used by the mathematics community.
I would imagine that there is a group of mathematicians out there that use haskell because it might be more consistent with ideas from mathematics. Is this true? 
What about APL? Do mathematicians today use APL or is that just a relic of the past?

REPLY [2 votes]: I'm in an MS in stats program and we don't use the programming languages as much as software packages like R, SAS, STATA, MATLAB and MiniTab. The closest to low a low level programming language is C-Sim which is used for simulating systems.
