For those of you here who dig into numerics, what are your preferences as far as language, style, etc.?
I prefer Fortran (using the 1995 or 2003 standards) and procedural style code.
I've seen a lot of numerical libraries in C++ lately and would not mind using C++ too much, but I think the syntax of an array based programming language like Fortran is more straightforward. Though C++ does let you overload a lot more operators than Fortran will.
