You guys don't use C++? I understand that Fortran is the gold standard for quants and scientific calculations, however I would think more engineers would use C. I took 77 and I know it has been updated long since then. I just haven't had to use it. Pascal, Matlab, C++, etc have all been adequate for my calculations. As far as the ISO 9126 is concerned, I would venture that C++ would be the best choice.
Nope, I took C++ in college as a tech elective and that was the last time I've used it. We have a lot of legacy software that was written in Fortran, the most common analysis tool Nastran was written in a Fortran derivative, and when it comes to manipulating large matrices of data Fortran seems to be just more straightforward to me.
Lots of guys use Matlab too. But that's pretty similar to Fortran from what I remember. A large piece of structure on the Ares I (RIP) was given to me and another guy to design. I wrote all the stress equations and he programmed them into a genetic algorithm he wrote in Matlab. NASA wanted us to write a paper as that was kind of a novel way of doing a first cut design and we ended way ahead of the scheduling curve, he was all into it because he's a PhD. I'm just a filthy contractor so I asked how much money was in it, when I heard it was only for the greater good of the engineering world I passed.
