I graduated less than a year ago - Matlab at the very least is quite
well-known, we got lessons about it (although I was the one kid who
used python for his matlab assignments...you can make do, with
matplotlib, google, opencv, and numpy.). I also believe they give
free/heavily discounted licenses to schools, hoping that after
graduation, those students are used to matlab and will try to make
their employers buy full-priced versions.

I don't know about Julia, though.
