Fortran, especially for matrix math with variable dimensions, can be faster than C. Fortran, (still last I heard) did not support pointers, which gives Fortran compilers the chance to exploit a very nice class of optimizations you can't use nearly as well in languages with pointers. I used to code C to be built with the "noalias" optimization, to get much of the speed of Fortran in C. But it required using an error prone subset of C without good error detection. -- https://mail.python.org/mailman/listinfo/python-list
