rkf45, a FORTRAN90 code which implements the Watt and Shampine RKF45 solver for systems of ordinary differential equations (ODEs).
The solver is a Runge-Kutta-Fehlberg algorithm for solving an ordinary differential equation, with automatic error estimation using rules of order 4 and 5.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
rkf45 is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and an Octave version and a Python version.
midpoint, a FORTRAN90 code which solves one or more ordinary differential equations (ODE) using the midpoint method.
NMS, a FORTRAN90 code which includes a wide variety of numerical software.
ODE, a FORTRAN90 code which solves a system of ordinary differential equations (ODE), by Shampine and Gordon.
TEST_ODE, a FORTRAN90 code which contains routines which define some test problems for ODE solvers.
