Personally, I think IDL presents an excellent mix of math capabilities and
graphics. Easy to produce numbers, easy to plot them.
Programs written in IDL can be 30-60 times slower than equivalent programs
written in FORTRAN, but if one uses extensive array manipulation facilities
execution improves tremendously (factors of 10).
