As someone with a budding interest in this, are you finding this stuff on the web? Any specific sites or books where you're finding these implementations?

  There are a few places that use FORTRAN extensively. The two I am aware of being Weather simulations and ESDU[1]. [1] https://www.esdu.com/cgi-bin/ps.pl?sess=unlicensed_1171113191142nfb&t=gen&p=home https://www.esdu.com/cgi-bin/ps.pl?sess=unlicensed_117111319...

  Netlib. Some good ones: * LAPACK (BLAS is there too) http://www.netlib.org/lapack/explore-html/ http://www.netlib.org/lapack/explore-html/ * QUADPACK (quadrature integration) http://www.netlib.org/quadpack/ http://www.netlib.org/quadpack/ * MINPACK (nonlinear solvers) http://netlib.org/minpack/index.html http://netlib.org/minpack/index.html * ODEPACK (ordinary differential equations) http://netlib.org/odepack/index.html http://netlib.org/odepack/index.html Most of the textbooks on numerical methods are not very approachable, but Carl Meyer's Matrix Analysis and Applied Linear Algebra text is a good start, as are Gilbert Strang's books.

    Note that SciPy wraps all of these in nice Python wrappers. (That's basically its reason for being.)

  Hairer's DOP853 is a differential equations solver that a lot of people seem to be enamored with: http://www.unige.ch/~hairer/prog/nonstiff/dop853.f http://www.unige.ch/~hairer/prog/nonstiff/dop853.f In this case someone took the old fortran code and modernized it a bit, yet again in fortran: https://github.com/jacobwilliams/dop853 https://github.com/jacobwilliams/dop853
