Fortran 95 It has the power of C, without the unsafe pointer arithmetics, almost the readability of Python, and all the array magic of NumPy. Almost every serious numerical library have bindings for Fortran. Calling Fortran from C: - Name mangling: usually lower-case with appended underscore. - Assumed-size or explicit shape arrays: just pass a pointer (cf. f2py). Avoid assumed-shape or deferred-size arrays in the interface to C. - Fortran 2003 ISO C bindings (cf. fwrap). > For instance, are there some nice C++ linear algebra libraries that map > closely to NumPy? Or is there some higher-level compiled array language that > looks something like NumPy code? The 'standard' linear algebra packages are BLAS and LAPACK, e.g. as implemented in ACML or Intel MKL. (Callable from C although implemented in Fortran.) Two comprehensive scientific C and Fortran libraries are IMSL and NAG.
