The code GAM numerically solves solves first order ordinary differential equations, either stiff or nonstiff in the form y'=f(x, y), with a given initial condition. The code GAMD is a generalization of GAM for the solution of Differential Algebraic Eq...
Fortran 77 code implementing a variable order-variable stepsize method for (stiff) initial value problems for ODEs. The order of the method varies from 4 to 14, according to a suitable order variation strategy.
Fortran 77 subroutine written by Hull, Enright and Jackson for the numerical solution of systems of initial value problems for ordinary differential equations.
