Hi,
some months ago, I proposed a library for solving ordinary differential equations, which can be found at
http://svn.boost.org/svn/boost/sandbox/odeint/
Is it possible to add odeint to the Libraries Under Construction page?
Best regards,
Hi, Sorry I miss your library. Do you agree with this Boost.Numeric.Odeint Author(s): Karsten Ahnert, Mario Mulansky Version: State: ??? Last upload: 2010/04/27 Links: Sansbox Documentation Categories: Math&Numerics Description:Odeint is a library for solving initial value problems (IVP) of ordinary differential equations. Mathematically, these problems are formulated as follows: x'(t) = f(x,t), x(0) = x0. x and f can be vectors and the solution is some function x(t) fullfilling both equations above. Numerical approximations for the solution x(t) are calculated iteratively. The easiest algorithm is the Euler-Scheme, where starting at x(0) one finds x(dt) = x(0) + dt*f(x(0),0). Now one can use x(dt) and obtain x(2dt) in a similar way and so on. The Euler method is of order 1, that means the error at each step is ~ dt[superscript 2]. This is, of course, not very satisfying, which is why the Euler method is merely used for real life problems and serves just as illustrative example. Let me know if you prefer other informations or modify the description? _______________________________________________ Done <https://svn.boost.org/trac/boost/wiki/LibrariesUnderConstruction#Boost.Numeric.Odeint> Vicente
