That's right indeed. Most engineering schools around here use Matlab.
Unfortunately what I see out there (or out here) is that usually the
school tries to buy a license but the students tend to use pirated
copies. I don't know if MathWorks uses the same strategy as Microsoft of
letting some people pirate and getting people addicted so as to buy the
software after leaving school.

Actually, some specialties use Scilab too. I for one swim against the
tide and use pylab with numpy.

Around here students are not allowed to use software for calculus stuff.
Maybe only for homework without the teacher's knowledge. Note: I can
only say that about the undergraduate Engineering courses in my college.

Or when the teacher forces to use Matlab, even if it's pirated. I've
heard of a graduate student whose teacher didn't want to help him
because he was using Scilab instead of Matlab.
